For instance, this one: Either we always remove the .exe suffix from
a file, or we have to check for each file with a .exe suffix, whether
it's executable or not.
In the first case, you get something like this:
$ echo foo > bar.exe
$ ls bar*
bar
$
Fortunately:
$ ls bar.exe
bar.exe
However, dependent of the intelligence of a script or application, the
suddenly missing suffix could result in trouble.
In the second case, the extra test for executability would be a big
performance hit, especially if you call `ls /usr/bin'. And you know how
we already have a lot of users kicking our asses for Cygwin's
performance.
So, whatever we do will result in problems for another group of users.
