Subject: git-prompt.sh: make $f local to __git_eread()
X-Git-Tag: v2.3.0-rc0~38^2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=9dd70e0a0d17aa66c2d95a05952dec05db156fe3;p=thirdparty%2Fgit.git

git-prompt.sh: make $f local to __git_eread()

This function uses (non-local) $f to store the value of its first parameter.
This can interfere with the user's environment.
