The variable was never meant to have more than one path concatenated
with ':' from day one.

In C code we've used it as a leading directory path to tack a
command name to form a path to give to exec(3), without any
intention to have it a list of paths, which is split at ':'.
sh-setup was doing "PATH=$GIT_EXEC_PATH:$PATH" without rejecting a
value in GIT_EXEC_PATH with a colon in it but that was merely being
lazy and made it "work" by accident.
