Revision a6253d107734c7ffa6d939307d87cf496795dc78 authored by Junio C Hamano on 25 May 2011, 19:23:44 UTC, committed by Junio C Hamano on 25 May 2011, 20:08:10 UTC
This function was introduced in 5b16360 (pretty: Initialize notes if %N is used, 2010-04-13) to check what kind of information the "log --format=..." user format string wants. The function can be passed a NULL instead of a format string to ask it to check user_format variable kept by an earlier call to save_user_format(). But it unconditionally checked user_format and not the string it was given. The only caller introduced by the change passes NULL, which kept the bug unnoticed, until a new GCC noticed that there is an assignment to fmt that is never used.
