[PATCH] emacs: Fix `notmuch-search-insert-field'

[David Edmondson <dme@dme.org>]

Compare the formatted version of the authors with the formatted sample
string rather than the un-formatted authors with the formatted sample
string.
---

Carl, please pull this in for 0.3. The previous fix didn't work
correctly when the authors string was one character shorter than the
length specified in the format string (presuming that the format
string is broadly unchanged from the default).
