[PATCH 1/2] emacs: add invisible dot instead of space at the end of notmuch-hello search box

[Dmitry Kurochkin]

This makes `show-trailing-whitespace' happy, i.e. it does not mark the
whole search box line as trailing spaces.

Since the dot is invisible, this change makes no visible difference
for `notmuch-hello'.
