  Log:
  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\}.
