[notmuch] [PATCH] Make the date parser nicer (v3 + 'now' keyword)

[Sebastian Spaeth]

The patch previously sent can be considered my final attempt to a nicer
date parser. In addition to some testing, I have updated the
documentation to reflect the new syntax, and I have also added the
keyword 'now' as a possibility. So 'date:2002..now' (all mails from 2002
until now) or 'date:now..31' (all mails that McFly sent to you between
now and the 31st of this month) should all work. Note that this is not a
sincere: 'since' replacement, as 2001..now won't find mails with
timestamps in the future.

The relevant 4 patches are in my git tree, git://github.com/spaetz/notmuch-all-feature.git then switch to branch 'dateparser':

59e9b56 remove superfluous debug statements from date parsing
4bdb0b0 allow 'now' as keyword for now
cf6c500 Adapt documentation to new date: syntax
d8d3d0b Make the date parser nicer. This is v3 and considered to be final (but the documentation).


Thanks,
Sebastian
