I'm pretty sure that bash has a limit on the length of a command line
which is different between Linux & Windows; I had a tool that was quite
happy with *.ad? on Linux but to make it portable I had to use a 'find'
approach, because the Windows (Cygwin) limit was considerably
smaller. This was actually a better solution anyway ...
