they're annoying *because* i can't do them!

for instance, suppose i've got a little sam expression that nicely
isolates particular subregions of text.  i can't work out a way to
match only characters which appear at the very beginning (or end) of
"dot".  kind of similar to ^ and $ except with respect to the
boundaries of the current selection.

e.g.  here's an expression that matches mbox entries in an acme Mail
window (tab replaced by \t):

	,x/.+\n(\t.+\n)*/y/^\(deleted\)-/g/./

it would be useful to be able to guard by message number on the
resulting message lines (without worrying about the contents of the
subject line).
