Yeah, but what to do afterwards? I can see this as an
* "git fetch", just like the updated "git pull", reads
$GIT_DIR/HEAD before it starts its work, and compares it with
$GIT_DIR/HEAD after it is done. If the --update-head-ok flag
is not given on the command line, and if the HEAD changed,
then barf and exit with non-zero status after reverting
$GIT_DIR/HEAD to its original value. If --update-head-ok is
given, none of the above check and revert happens.
* "git pull" calls "git fetch" with the extra flag, and does
its thing the current way.
So if you are calling from the command line, "git fetch linus",
when you were still on "linus" branch (which you do not normally
do but just to prevent mistakes), it would trigger the check and
your $GIT_DIR/HEAD would stay intact. If you stayed on your own
branch, "git fetch linus" would continue to just fast forward
"linus" head without touching the working tree.
Come to think of it, it may be cleaner to simply forbid
fast-forward fetching into the current repository (whether it is
"git fetch" or "git pull"). At least in your workflow you do
not do that ever anyway.
