I've had some time to look into this problem again after having updated
Cygwin to the latest and greatest.  Indeed, when

/usr/share/locale/locale.alias

gets renamed, the problem also goes away.  This is great because I don't
really need the locale aliases for anything.  Btw, my laptop got
upgraded to Win10 1909 (Enterprise) in the meantime, so the issue isn't
specific to 1803 as was supected earlier.

I then tried to figure out what exactly causes the problem and it turns
out that it's the _presence_ of this file with the additional condition
that it must not be owned by the user starting the mintty/shell.  Since
I install Cygwin on my work laptop with a different (admin) account and
not my (non-admin) user account, that explains why I am seeing the
problem there and not on other machines.  Before you are going to
suggest that it's the admin vs. non-admin rights: no, if I create a
locale.alias with my user account (either as an empty file or a copy of
the backup file), then the admin account is unable to start a shell in
mintty successfully.  I have no idea why the ownership of a file that
onnly should get read (and is readable by everyone) would have the
effect I'm seeing, but maybe that gives the clue on where to look for a
fix.
