Thoughts below partly for my own reference, and partly in case anyone
else – including but not limited to Panos! – manages to take things
further before I do.

I can't see anything obviously wrong here. There's two key oddities
that might be causing problems, though:

- Cygwin is installed in `C:\Program Files\Cygwin`; that _should_
work, but it's atypical, and spaces in filenames are a common source
of problems.

- This is a relatively old installation; I've not checked anything
else, but Cygwin Git v2.21.0-1 was released in May 2019 and there have
been a bunch of updates since then. I can't remember anything with
these symptoms from that time, however.

I'm also curious about the Git configuration here, as I can see a
bunch of ways that could cause problems. I don't have the Cygwin bin
directory in my path to test this immediately, but for example `git
branch -a` will try to call a pager – `less` by default` – so I could
imagine there being a PATH problem or similar that's resulting in a
duff pager call that's eating the output.
