I think git can't assume the existence of bash unconditionally, neither
in its scripts, nor in its tests (the exception being the tests on
bash completion, of course). This script probably need to be re-written
to be a valid POSIX shell script.
It almost is, anyway, apart from the nits below ...

Just FYI: the double quoting here (and in several variable assignments
below) is redundant. You can portably write it as:
alias=$1
and still be safe in the face of spaces and metacharacters in $1.
I'm not sure whether the Git coding guidelines suggest the use of
quoting in this situation though; if this is the case, feel free
to disregard my observation.

I believe this should be rewritten as:
GIT_DIR="$url/.git"; export GIT_DIR
in order to be portable to all the POSIX shells targeted by Git.

The '-n' option to echo is not portable. To create an empty
file, you can just use

Useless double quoting (my previous observation about Git coding
guidelines applies here as well, of course).

Better avoid the tricky {foo,bar} bashism:
git fast-export --use-done-feature \
--import-marks="$testgitmarks" \
--export-marks="$testgitmarks" \
$refs | \

I'd put an explicit exit status here, for clarity (this is a matter
of personal preference, so feel free to disregard this nit).
