[PATCH 1/9] lei q: --save preserves relative time queries

[Eric Wong <e@80x24.org>]

Somebody may want a saved search which consistently asks for
messages within a rolling time period window.  In other words,
we want to support using "lei q --save dt:last.week.." and keeps
the "dt:last.week.." relative to whenever "lei up" is run.  This
ensures relative date-time specifications get used in the future
rather than converting into an absolute date-time from the
initial "lei q" invocation.
