Subject: git-gui: Display message box when we cannot find git in $PATH
X-Git-Tag: gitgui-0.8.4~8
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=183a1d1496921e16d316ac523146385af39fcdb0;p=git.git

git-gui: Display message box when we cannot find git in $PATH

If we cannot find the git executable in the user's $PATH then
we cannot function correctly.  Because we need that to get the
version so we can load our library correctly we cannot rely on
the library function "error_popup" here, as this is all running
before the library path has been configured, so error_popup is
not available to us.
