From: Miklos Vajna Date: Sat, 27 Dec 2008 23:03:57 +0000 (+0100) Subject: parse-opt: migrate builtin-apply. X-Git-Tag: v1.6.2-rc0~134^2~1 X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=f26c4940c4c7942a95058d9aaef7b01967085a60;p=git.git parse-opt: migrate builtin-apply. The only incompatible change is that the user how have to use '--' before a patch file if it is named "--build-fake-ancestor=something".
