Even though it is POSIX, using backslashed grouping in 'grep' isn't
portable. It fails at least on Solaris 8, and you have to do:

  egrep "^(author|summary) "

instead. Of course, I can't get your test to pass even with that change,
but I think that is just a broken iconv on Solaris.

Yuck.  Solaris 8 /usr/bin/grep does not even grok "-e", so we cannot do a
more obvious:

	grep -e "^author " -e "^summary "

Do people build with NO_EXTERNAL_GREP on older Solaris?

git-submodule.sh uses grep "-e" to look for two patterns and I suspect
older Solaris would have the same issue.
