The patch replaces all (message (buffer-string)) calls in emacs
tests with (princ (buffer-string)). This avoids accidentally
interpreting '%' as format specifiers and makes code simpler
because we do not need to capture stderr.
Also, the patch works around an Emacs (23.3+1-1 on current Debian
Unstable) segfault in "Ensure that emacs doesn't drop results"
test. Note: the segfault does not happen on every test run.
Though, it seems to be consistently reproducible if the test uses
300 messages instead of 30. Hopefully, it is the crash described
in Emacs bug #8545 [1] which is already fixed.

With the previous commit, unexpected output before or between search results
would be displayed. However, trailing junk from the "notmuch search" output
would still be silently swallowed.
The most common case for an error message from "notmuch search" would be
an invalid command-line, and in that case, there would be no search results
and the trailing error message would get swallowed.
We fix the process sentinel to check for leftover data and add it to the
final buffer. We also add a test case to ensure this works.
Rather than silently swallowing unexpected output, the emacs interface will now
display it. This will allow error messages to actually arrive at the emacs
interface (though not in an especially pretty way). This also allows for easier
investigation of the inadvertent swallowing of search results that span page
boundaries (as demonstrated by the recent added emacs-large-search-buffer test).
The page-boundary bug has been present since a commit from 2009-11-24:

Many thanks to Thomas Schwinge for tracking that bug down and
contributing the test for it.
The new name is more descriptive of the bug being tested. Also, the test
is rewritten slightly so that it's much more plain to see how the bug
manifests itself, (that messages are droped from the emacs result at
regular intervals). Primarily, this is by collapsing the large blobs
used to inflate the message subjects.
