Log Message:
Pull up missing "'" from gnats trunk, since netbsd-5 sh(1) trips over
the missing quote -- first half of

2006-06-30  Stephane Chazelas  <Stephane@artesyncp.com>

	* edit-pr.sh: missing quote on line 172 (it's OK for the
	Bourne shell and AT&T ksh based sh, but not other shells), and
	the tr syntax, though POSIX is causing trouble with Solaris
	tr.  Closes: PR#613
