Subject: [PATCH] [project @ 2004-10-01 03:52:57 by wolfgang] Replace \? by
 \{0,1\} in the sed regular expressions, as the former does
 not work with Mac OS X's (= BSD's) sed.

I'm a bit confused by the situation here:
According to Mac OS X man pages, the latter syntax is part of the
POSIX 1003.2 standard for basic regular expressions, while the former
is not. According to the manpage installed with my Gentoo linux, neither
is in the POSIX standard.

However, GNU sed accepts both \? and \{0,1\}, while Mac OS X's sed accepts
only \{0,1\}.
