2efc77d2fd Fix warnings generated by gcc 4.6.0 about variables set but not
thereafter read. Most of these changes are just removal of pointless
stuff or trivial reorganisations; one change is actually substantive,
and fixes a bug in Keen's clue selection (the variable 'bad' was
unreferenced not because I shouldn't have set it, but because I
_should_ have referenced it!).

980880be1f Add a function to every game backend which indicates whether a game
state is in a solved position, and a midend function wrapping it.

(Or, at least, a situation in which further play is pointless. The
point is, given that game state, would it be a good idea for a front
end that does that sort of thing to proactively provide the option to
start a fresh game?)

8589cb3a0c Patch from Mark Wooding to add antialiasing-safety in repeated
redrawing of inequality signs in Unequal (which are redrawn when
they change colour).

50b6e0d708 Chris Boyle reports an off-by-two error ('a Qui-Gon Jinx' :-) in
difficulty selection in Unequal's solver. I suspect I missed this
when I refactored latin.c and its callers.

f55dc67f43 Fix from James H: the shared code between drawing and printing
should use state->adjacent rather than ds->adjacent, because the
latter won't be initialised in printing mode.

b629e34beb Fix bug causing array overrun. Only seemed to be showing a symptom
on Windows, presumably because the data after the array was harmless
elsewhere.

a79ab34941 Normalise Unequal (and latin.c) so that solver diagnostics start
their coordinate from 1 rather than 0, for consistency with Solo.
(My geek instincts would rather work from 0, but I've generally
found that puzzle users sending me email tend to prefer 1.)

189f833980 Refactor latin.c to make it easier to reuse. Instead of client
programs having to clone the latin_solver() function and insert
their own extra deduction routines, they can now just _call_
latin_solver with enough parameters to let it fit its own deductions
into their difficulty framework and call a set of provided function
pointers to do user deductions. Modified Unequal to work in the new
world, of course.

b9c22e5cac New mode for Unequal, from James H. In this mode, called 'Adjacent',
the < and > clues are replaced by bars separating every pair of
squares whose contents differ by exactly 1. Unlike standard Unequal,
which presents only a subset of the available clues, in Adjacent the
clues are _all_ present, so you can deduce from the absence of a bar
that the two numbers it would separate are _not_ consecutive.

2bdabe31cf Jonas Koelker points out that the backspace key didn't work in GTK
Guess, because Guess expected ^H whereas GTK generated ^?. Other
puzzles that use Backspace do it by being prepared to see either,
which seems wasteful. Now the midend normalises both into ^H, so
front ends can generate whichever they like while puzzles can
safely just look for ^H.

4d79c71517 Reorder if statements in Unequal's interpret_move() so that presses
of 'h' and 'm' are treated as digits if a square is selected, and
only treated as special commands otherwise. This renders very large
games (just about) playable.

Idea from Ben Hutchings's collection of Debian patches, although I
had to redo his (trivial) patch myself since the code has changed
recently.

(Addendum after committing: hmm, I see Jacob already applied the
original version of the patch a while back. Looks as if the recent
keyboard control change reintroduced the problem. Still, re-fixed
now.)

4a202808ee Patch from James H which adds keyboard cursor support to Unequal,
and also updates the docs for both that and the Mines cursor support
in r8402.

808495cb41 Apply "103_fix-unequal-digit-h.diff" from the Debian package:
Unequal 18x18 or above was unplayable due to a clash with the undocumented
"H" (hint) key. Resolve the clash by making the hint function only fire
when no square is selected.

a7431c0b7c New infrastructure feature. Games are now permitted to be
_conditionally_ able to format the current puzzle as text to be sent
to the clipboard. For instance, if a game were to support playing on
a square grid and on other kinds of grid such as hexagonal, then it
might reasonably feel that only the former could be sensibly
rendered in ASCII art; so it can now arrange for the "Copy" menu
item to be greyed out depending on the game_params.

To do this I've introduced a new backend function
(can_format_as_text_now()), and renamed the existing static backend
field "can_format_as_text" to "can_format_as_text_ever". The latter
will cause compile errors for anyone maintaining a third-party front
end; if any such person is reading this, I apologise to them for the
inconvenience, but I did do it deliberately so that they'd know to
update their front end.

As yet, no checked-in game actually uses this feature; all current
games can still either copy always or copy never.

9287d95d08 General cleanups patch from James H:
- missing static in filling.c
 - better robustness in execute_move() in filling.c
 - remove side effects in assert statements
 - remove rogue diagnostic in galaxies.c
 - remove // comment in map.c
 - add more stylus-friendly UI to Pattern
 - bias Unequal towards generating inequality clues rather than numeric

15f70f527a Dariusz Olszewski's changes to support compiling for PocketPC. This
is mostly done with ifdefs in windows.c; so mkfiles.pl generates a
new makefile (Makefile.wce) and Recipe enables it, but it's hardly
any different from Makefile.vc apart from a few definitions at the
top of the files.

Currently the PocketPC build is not enabled in the build script, but
with any luck I'll be able to do so reasonably soon.
