Hi all,

I've been trying for a few weeks to try to get this to work, and the /bin/sh
keeps snagging the command line before passing it to pkg_info

I'll use a different shell if I need to, but since I got everything except
this one thing working, i'd rather keep it in sh

In the shell script, i have a
  pkg_info -qLx "^$PKG-[0-9,._]+$"
also tried (-X)tended regex instead of the standard rege(-x).

sh keeps erroring out saying various $" isn't a valid variable name, or
pkg_info doesn't find the anything there.  And it does exist.  This all came
around with me trying to automatically update a bunch of ports.  xorg-fonts
is outdated, but xorg-fonts-100dpi or xorg-fonts-75dpi isn't.  So the regex
returns multiple values (as above).  I just want the first, hence the
anchors.

Any ideas on how to get sh to let pkg_info see everything?  Various escaping
around the end $ just doesn't work.  I'll keep working on it, but i'd like
to see how you all would suggest getting it to work.

Thanks!
