2014-03-26 Mike Frysinger <vapier@gentoo.org>.
* configure.ac - Clean up most of the --with/--enable flags:
- use AS_HELP_STRING instead of writing the text ourselves;
- use the normal enable_xxx var AC_ARG_ENABLE creates for us;
- delete duplicate checks in a few places (due to previous cleanup);
- unwrap some macros/var assignments;
- delete trailing whitespace;
- delete old --enable-all flag;
- fix quoting on a lot of vars that come from the user;
- use AC_MSG_* helpers instead of raw `echo`.
2014-03-24 Benno Schulenberg <bensberg@justemail.net>
* doc/syntax/gentoo.nanorc - Match more files, add a trailing
whitespace check, and EAPI=5 updates. Patch by Mike Frysinger.
