+
+ * doc.c (Fsubstitute_command_keys): Clarify that \= really only

+
+2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
+
+ Fix minor problems found by static checking.
+ * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
+ (elsz): Now a signed constant, not a size_t var. We prefer signed
+ types to unsigned, to avoid integer comparison confusion. Without
+ this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
+ "cannot optimize loop, the loop counter may overflow", a symptom
+ of the confusion.
+ * indent.c (Fvertical_motion): Mark locals as initialized.
