Subject: emacs: add notmuch-version.el.tmpl and create notmuch-version.el from it
X-Git-Tag: 0.18_rc0~45
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=cab1415a94f09c529ca7323904c5a159c996cbe0;p=notmuch.git

emacs: add notmuch-version.el.tmpl and create notmuch-version.el from it

The notmuch cli program and emacs lisp versions may differ (especially
in remote usage). It helps to resolve problems if we can determine
the versions of notmuch cli and notmuch emacs mua separately.

The build process now creates notmuch-version.el from template file
by filling the version info to notmuch-emacs-version variable.
