[jamming] Problems with listing files in directories

[Alen Ladavac]

Not sure exactly what could be wrong with this version. Didn't the
original version I posted work ok?

But clearly the comment:

>   # filter so that only real files are included (skip current dir, parent
> dir and all other dirs)

is wrong, as you never test against inclusion of subdirs. Also note
that [ GLOB $(1) : * ] has a quirk that if $(1) is a file, it will
return that file.
