[PATCH 1/3] test: add known broken tests for from: and subject:

[David Bremner]

Given we want 'a b' to parse as 'a AND b', then for any
probabilistic (free text) prefix foo:, we should also get 'foo:a
foo:b' expanding to 'foo:a AND foo:b'. Currently this is not true due
to the implimentation of regex fields.
