combine-diff.c: type sanity.
In diff_tree_combined(), show_log_first boolean is initialized with rev->loginfo (pointer to a string); the intention is that if we have some string to be emitted we would want to remember that fact. Picky compilers are offended by this, so make the expression a bit type-safer. Signed-off-by: Junio C Hamano <junkio@cox.net>
