Does anyone see a way to make it more efficient with a POSIX shell?
Yes. Eric's earlier message convinced me that grep shouldn't rely on
Autoconf guaranteeing a shell that supports substrings in parameter
expansion, so I came up with the attached patch (which keeps the shell
efficient with a POSIX shell) and pushed it before I got around to
reading your message. I tested on Solaris 10 with the shell
artificially set to /bin/sh, so I'm marking this as done.
From an Autoconf point of view it might be nice to have a good way to
say "I need a POSIX shell" or at least "I need a shell that does
substrings", but that's merely a wishlist item.
