Subject: perl/Git.pm: Honor SSH_ASKPASS as fallback if GIT_ASKPASS is not set
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=8f3cab2b4d7b6da8b69eea730e5774dcb208c50f;p=git.git

perl/Git.pm: Honor SSH_ASKPASS as fallback if GIT_ASKPASS is not set

If GIT_ASKPASS environment variable is not set, git-svn does not try to use
SSH_ASKPASS as git-core does. This change adds a fallback to SSH_ASKPASS.
