[PATCH] search: fix argv handling of quoted phrases

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

This fixes both an old bug in "lei q" argv handling and one
recent regression introduced with the change to use approxidate.

Field prefixes are also handled correctly inside parenthesized
statements when the field follows "(" without a separation
character.

Fixes: fbb7ccabbf54a405 ("lei q: use git approxidate with d:, dt: and rt: ranges")
