What kind of benefit are you envisioning out of this?
The purpose of tests is to detect mistakes and spot regressions.
A change to the 'git version X.Y.z' string would be a regression, as
spotted earlier, as it conflicts with expectations of standard
programmes such as git-gui.
Sorry, but I do not follow.
A released version says "git version 220.127.116.11". In a month or so,
I'll have another one that says "git version 1.8.3". Or I may
decide to bump in preparation for 2.0 and it may identify itself as
"git version 1.9".
Neither of which no existing "program such as git-gui" has ever
In what way is that a regression?
But they both pass the test and test suite, yes? And even if you use
git-gui with them, git-gui will not barf on start up, which it would if
the version string fails my test.
Passing the test suite should be a reasonble guarantee that co-tools
will work, including those that check for version. This is a check for
that version string.
However if someone creates "My Special Git Version 1-9-3 (Index
V7b)", and here I'm suggesting they may have other special changes, then
the version check will tell them that even when they have fixed their
special changes to pass the other parts of the test suite, other
co-tools could barf.
Its about pushing the piece of string from the users end ;-) It also
stops others trying to change 'git' to 'Git' within this message, just
as I did.
 my first draft had 'you', but that is not a reasonable starting
position. It's more about *others* attempting to create release
versions, which announce their name, that we expect to be compatible
with say git-gui (via the rest of the test suite), and need to check
