Applied to master. I'm curious how many such message ids there are in
the wild. It is not particularly hard to fix this in the query
parser(s), but it is a bit tedious (e.g. a new field processor would
need to be added for the id prefix in the infix query processor).

[PATCH] test: add known broken test for message-id with embedded spaces.

[David Bremner]

According to my reading of RFC5322, there is an obsolete syntax for
Message-Id which permits folding whitespace (i.e. to be removed /
ignored by parsers). In [1] Paul Wise observed that notmuch removed
whitespace on indexing, but does not do any corresponding
normalization of queries. Mark the latter as a bug by adding a failing
test.
