Indeed. I started to give some of the history in the commit message, but
it was nearly 3am, so I punted with the 'see also commits 6fd1106aa4 and
c51c0da222' ... ;-)

Ah, OK. I only looked at my (64-bit) MSYS2 build, which fails
exactly the same as cygwin. Hmm, wait, let me just rebuild on
MinGW64 ... indeed it passes (well it passes t7400.20, but it
fails on t7400.11, 61, 63, 87 and 89)!

Indeed. Also on MSYS2 (exactly as on cygwin):
ramsay@satellite MSYS $ ./t7400-submodule-basic.sh -i -v
...
ok 19 - submodule add with ./, /.. and // in path
expecting success:

OK, I'll re-roll the patch (tomorrow, it's late again).
Thanks.
