Re: gitk from subdirectory

[Junio C Hamano <gitster@pobox.com>]

"git log" family of commands, even when run from a subdirectory,
do not limit the revision range with the current directory as
the path limiter, but with double-dash without any paths after
it, i.e. "git log --" do so.  It was a mistake to have a
difference between "git log --" and "git log" introduced in
commit ae563542bf10fa8c33abd2a354e4b28aca4264d7 (First cut at
libifying revlist generation).
