[PATCH] test: replace $PWD with YYY in emacs & emacs-show tests

[david at tethera.net]

From: David Bremner <david at tethera.net>

When executed command line is written to *Notmuch errors* buffer,
shell-quote-argument will backslash-escape any char that is not in
"POSIX filename characters" (i.e. matching "[^-0-9a-zA-Z_./\n]").

Currently in two emacs tests shell has expanded $PWD as part of
emacs variable, which will later be fed to #'shell-quote-argument
and finally written to ERROR file. If $PWD contained non-POSIX
filename characters, data in ERROR file will not match $PWD when
later comparing in shell. Therefore, in these two particular cases
the escaped $PWD is replaced with YYY in ERROR file and expected
content is adjusted accordingly.

The commit message is shamelessly boosted from Tomi's patch.  To be
honest I didn't notice that Tomi had already sent a patch when I
started on this, and then I was too stubborn to stop. I'm not sure
which is better. It depends whether you think the cosmetic stuff is an
improvement, or just gratuitous. For what it's worth (not that much as
Tomi points out) this should work ok with spaces in the path. Better
to light a candle than to curse the darkness, etc...
