Just found that Git Gui checks for the version number (line 936)

    if {![regsub {^git version } $_git_version {} _git_version]} {

and then parses for the dot separated digits etc.

So looks like the version string change would be a problematic 
regression.

Given the change elsewhere of 'Usage:' to 'usage:' it looks like I 
should drop this patch.
