From f327dbced25a3c6fcc0b84d2d6adffa9343b09f0 Mon Sep 17 00:00:00 2001
From: Mark Wooding <mdw@distorted.org.uk>

Subject: Shell utilities: Guard against expr' magic tokens.

Some words, e.g., `match', are special to expr(1), and cause strange
parsing effects.  Track down all uses of expr and mangle the arguments
so that this isn't a problem.
