This list is there to avoid the costly operation of opening the file
and reading its first two bytes; files with other extensions will be
read and their executability determined by the magic signature.  So
the list only includes extensions you see most frequently on a typical
DOS/Windows system.

If somebody thinks that a few more extensions should be added, I don't
mind, but please remember the downside: the risk to identify
non-executable files as being executable, just because some Windows
application decided to usurp one of these extensions.
