Subject: configure: check that the version of emacs we may have is at least 24
X-Git-Tag: archive/debian/0.29_rc0-1~141
X-Git-Url: https://git.cworth.org/git?p=notmuch;a=commitdiff_plain;h=5e4437237365373ddb90abae7d7a62ecb36034e2

configure: check that the version of emacs we may have is at least 24

This also effectively drops support to Emacs version 23, which was
deprecated in version 0.23.2 (2016-11-20) and did not entirely work
any more.
