PATCH: meaning of before/since for date glob qualifiers completion

[Oliver Kiddle <opk@zsh.org>]

This is a variant of the github #80 from Vincent Bernat.

Descriptions of just "before" and "since" are perhaps ambiguous because
it can depend on your perspective as to whether the specified date is
before/since the file time-stamp or the other way around. For
completion, we tend to be focussed on the value entered but in actual
usage the age of the files is perhaps foremost in people's mind.

This inverts them as per the github PR but also adds a brief
parenthetical. I'd prefer to keep the descriptions as brief as possible
because _dates expects most of the terminal is available to it.
