Gareth is correct.
If you do this:
touch delme
ls *.*
You'll see that delme is not listed. Cygnus wildcard expansion follows
UNIX rules, not MS-DOS rules. You can't (easily) create an actual
'delme.' file on Windows. So, "delme." is the same thing as "delme", i.e.
if you perform an ls on the directory, you'll see a file called "delme"
not "delme.".
