Call XKeysymToString() much less, it leaks.
src/ChangeLog addition:
2012-01-08 Aidan Kehoe <kehoea@parhasard.net>
* device-x.c:
* device-x.c (syms_of_device_x):
Move #'x-keysym-on-keyboard{,-sans-modifiers}-p to Lisp, the hash
table no longer stores the X keysyms, so we need to manipulate any
strings we have been handed.
* event-Xt.c (x_has_keysym):
Don't call XKeysymToString() here, it leaks; trust
x_keysym_to_emacs_keysym() instead.
* event-Xt.c (x_keysym_to_emacs_keysym):
No longer leak when looking up the strings for keysyms of the form
UABCD.
lisp/ChangeLog addition:
2012-01-08 Aidan Kehoe <kehoea@parhasard.net>
* x-init.el:
* x-init.el (pseudo-canonicalize-keysym): New.
* x-init.el: Move #'x-keysym-on-keyboard-sans-modifiers-p,
#'x-keysym-on-keyboard-p here from device-x.c, some string
manipulation it now needs to do is far easier in Lisp.
* x-win-xfree86.el:
* x-win-xfree86.el (x-win-init-xfree86):
No longer call #'x-keysym-on-keyboard{,-sans-modifiers}-p,
implement it ourselves cheaply.
