Emil Sit a4227dfec1 listcon/listproj: Work around bug in older GNU greps. ...

Commit df4f9150 introduced the use of "grep -w -o".  This
combination was broken from the introduction of -o (in 2001) until
subsequent release of GNU grep 2.5.3 in 2007---see changelog for
2005-11-10.  In particular, OS X uses a pre-2.5.3 version
of GNU grep.

Work around by replacing with two greps: one to find maximal
strings with @s in them (still relying on -o) and the second to
extract contexts.

Reported by Jon Smajda <jon@smajda.com>; fix developed
in conjunction with Philippe Teuwen <phil@teuwen.org>.
