Subject: Save errno in handle_alias()
X-Git-Tag: v1.4.1-rc2~2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=47e5c0ca2cabb406518dda5c09432dc996f7ef2b;p=git.git

Save errno in handle_alias()

git.c:main() relies on the value of errno being set by the last attempt to
execute the command. However, if something goes awry in handle_alias(),
that assumption is wrong. So restore errno before returning from
handle_alias().
