Globbing wouldn't work without substitution being done first where there are variables etc in the line. The option allows me to have the benefit of globbing (at the expense of substition) in these cases without having substition for everything. So the effect is that only globbed things are substituted hence the name subst-only-globs. If anyone can think of a better name, its easily changed.

A patch for this follows then.
