devel/try-emacs-mua.sh provides an easy way to try and experiment with
the notmuch emacs client provided in emacs subdirectory of notmuch
source tree.
User is required to choose whether to run emacs with -q, -Q or neither
-- and experienced ones may add other command line options, like
'-f notmuch'.
This script ensures that no .el files are newer than corresponding .elc
files so that user (/developer!) does not accidentally experiment with
outdated elisp files. The emacs variable to have the same effect,
`load-prefer-newer' is not available until emacs 24.4.
The *scratch* buffer is filled with some code user can execute before
running notmuch code.

Addressed David's comments in id:87d1xdtim1@maritornes.cs.unb.ca
with 2 updates:
1) removed "address completion insinuate"
2) added code to initialize package system when using -q or -Q
