Revision 251df09be3af658404f5f5f670a013d5806645d4 authored by Matthieu Moy on 09 March 2011, 20:52:15 UTC, committed by Junio C Hamano on 09 March 2011, 22:28:24 UTC
The --max-count limit is implemented by counting revisions in get_revision(), but the -S and -G take effect later when running diff. Hence "--max-count=10 -Sfoo" meant "examine the 10 first revisions, and out of them, show only those changing the occurences of foo", not "show 10 revisions changing the occurences of foo". In case the commit isn't actually shown, cancel the decrement of max_count. Signed-off-by: Matthieu Moy <Matthieu.Moy@imag.fr> Signed-off-by: Junio C Hamano <gitster@pobox.com>

# If the GIT_DIR does not look like the right correct git-repository,

# Having this variable in your environment would break scripts because
# you would cause "cd" to be taken to unexpected places. If you
# like CDPATH, define it for your interactive shell sessions without
