Bloody heck. Thank you, Philip. I'd never have figured that "$" interpre-
tation would work on the variable name to the left of the question marks,
but I tried it and it does. It's immeasurably better than either of my
suggestions.
In our private exchange about it, Philip added that the above would not
work if there were a newline in the name of the variable in the previous
value of MATCH, but a variable's name shouldn't have an embedded newline
anyway in any shell I know of. Still, if it should,
* $ $MATCH ?? ^^\/[.$]+
The newline problem is not with newlines in the variable name but
rather in the value of the indexed variable (the variable whose name is
in MATCH). David had a thinko on that last example. It should have
been:
* $ $MATCH ?? ^^\/(.*$)*
