[PATCH] emacs: allow to set RETAIN-STATE for `notmuch-show-refresh-view' interactively

[Dmitry Kurochkin]

The notmuch-show view refresh function (`notmuch-show-refresh-view',
bound to "=") accepts an optional RETAIN-STATE argument.  The patch
allows to set this argument interactively by using "C-u =".
