[PROTO] possible solution for "Race condition for '*' command"

[Pieter Praet]

Thanks Austin!

Unfortunately, your patch causes *all* Message-Id's in the thread to be
appended, as opposed to only the ones matching the query:

#+BEGIN_EXAMPLE
$ notmuch search tag:inbox AND from:amdragon at mit.edu
thread:0000000000002777 Yest. 19:17 [1/3] Austin Clements| Pieter Praet;
[PATCH 2/2] [RFC] possible solution for "Race condition for '*' command"
(inbox replied sent to-me x/notmuch)
id:"CAH-f9WticM4EN8F1_ik_-mcBcBtrXwSpO+Drbtp7=UN7McECrg at mail.gmail.com"
or id:"87zkkwydag.fsf at praet.org" or id:"20110703171743.GL15901 at mit.edu"
#+END_EXAMPLE

As you can see, according to matched/total ("[1/3]") only a single
message matches the query, yet all 3 MsgId's are returned.

If this were to be corrected (probably a trivial change, but I'm pretty
much oblivious as to the what and where of it), the following patch
series should work as intended.

The "--stdin" option works as expected (and ARG_MAX is indeed a very
valid concern with this particular use case), but I haven't yet gotten
around to making use of it from the Emacs UI as this would require some
screwing around with `notmuch-tag' and `notmuch-call-notmuch-process',
and it's still pretty early I-).

Peace
