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\}.
