It seems that the escape is not required, although every example I saw
on the Internets uses it (one copying the another, I guess.)

What I've discovered while investigating your commentary is that the
[^.] syntax is not POSIX and some shells (posh) does not admit it. The
syntax required by POSIX is [!.]. I checked that .[!.]* works as
expected on GNU/Linux and on Windows (MSYS2 and cmd.exe calling git and
grep). It doesn't work on Eshell, but that doesn't count.

On a few days I'll commit the patch using the [!.] syntax, if nobody
objects to it.
