That's nice one, as has been pointed, but let's make a step back to the
definitions and see what we have on hand, before advancing in this way?
"Extension is a part of the file name, after last period".
Two conclusions we can make from it:
1. Extension itself can't contain a period.
2. The file can't have an extension only and only if it has no periods in the
name.

Doing this kind of magic, you only ease the burden of file handling for cygwin
in windows, but by a little margin, IMO.
File name could have more dots than what you can imagine...

Also, this same trick could be applied to the Explorer as well.

REGEDIT4

[HKEY_CLASSES_ROOT\.\shell\Open\command]
