Subject: Eliminate an unnecessary chdir("..")
X-Git-Tag: v1.6.0-rc0~121^2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=450f437fb0fe276a6e946c281c768118e39dc9e7;p=git.git

Eliminate an unnecessary chdir("..")

In the case where setup_git_directory_gently fails, avoid the last
chdir("..") by moving it after the ceil_offset check.
