No, even if that looks weird. But think about what happens. ls calls
readddir. readdir returns "python2.7.exe". The matching is not done by
Cygwin, but by the shell. And python2.7.exe simply doesn't match
"python[2-9].[0-9]".
Nothing Cygwin can do about, unless we suppress the .exe suffix in
readdir/realpath/readlink output just like we do with the ".lnk" suffix
for the old winsymlink symlink style.
