yesyes ;D

This patch has 2 (additional) improvements: 

1) it removes the unportable sed -i (GNU feature) 
2) informs developer from which files the comparison contents are coming from

There is also one problem: the notmuch_emacs_error_sanitize() expects
that the notmuch-command in question is always .../notmuch_fail. This 
doesn't look good in a (generic) function.

One option would be to change the regexp in notmuch_emacs_error_sanitize()
to something like:
>   -e 's|^\(command: \)[^ ]*/|\1YYY/|'

i.e. just touch the ^command: line, remove all nonspace(*) chars until last
slash (/) before space.

(*) we're back with this 'space' thing, but I dont's see any alternative.
Using set of allowed chars is impossible as users may have e.g. utf-8
chars in their paths...
