Re: how can I skip globbing through SCCS subdirs?

The bad news is that ** handling bypasses most of the pattern code,
i.e. you can't actually exclude things while the ** list is being
expanded.  The good news is that in the ~ part of the pattern, /'s are
not special.  This means you can exclude SCCS directories like this:

ls **/*.c~(*/)#SCCS/*

The (*/)# is a trick so that top level SCCS directories are ignored as
well as any /SCCS/ bits in the middle somewhere.

By the way, as this shows, ~ has lower precedence than /.  That's
because it was originally intended that you only use ~ the way I've
just done, i.e. with the whole pattern.  However, you can now group it
using parentheses if you avoid using ** inside the parentheses (so it
doesn't solve your problem here).

No, sorry.
