Thanks for looking into this code deduplication!
Well these two parts of the code are subtly different, though.
When applying this patch to origin/master (3bc53220cb2 is the
last time I fetched from Junio), then
$ make
$ cd t
$ prove --timer --jobs 25 ./t[0-8][0-9]*.sh
... lots of output...

When then running one of them with debug output
(See t/README for the debug flags, I remember divx,
the video format as a sufficient set of flags to get enough debug output)

So I think we're missing to create the directory? (Just guessing)
Maybe we need to have 2293f77a081
(connect_work_tree_and_git_dir: safely create leading directories,
part of origin/sb/checkout-recurse-submodules, also found at
https://public-inbox.org/git/[email protected]/ )
first before we can apply this patch.
Thanks,
