It's possible but it requires a big bunch of changes inside of
Cygwin. Allowing trailing dots (and spaces) in filenames just
happened coincidentally as a result of using the NT native function
NtCreateFile to create files. In contrast to Win32 functions, NT
native functions don't mess around with filenames.
The disadvantage of creating these filenames is that all other Win32
applications are unable to deal with these files. As you probably
have found out by yourself, it's not possible to delete, move or rename
these files in Windows Explorer.
