Subject: notmuch show: Fix to work with any search string rather than just a thread ID.
X-Git-Tag: 0.1~568
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=494c74229bb8bdfc8571ce5de20a7beb0333c5f2;p=notmuch.git

notmuch show: Fix to work with any search string rather than just a thread ID.

The more general command is more consistent, and more useful.

We also fix "notmuch search" to output copy-and-pasteable search terms
for the thread with "thread:" prepended already. Similarly, the
message-ID in the output of "notmuch show" is also now printed as a
valid search term, ("id:<message-id>" rather than "ID: <message-id>").

Naturally, the emacs code is also changed to track these changes.
