search: skip a match on the magic line, as it is a just convenience line

As the magic line isn't really a line (it is not counted in the number
of lines read and written), and nothing is on it (not even a newline),
it doesn't make sense to allow any regex, like ^ or $, to match it.

This fixes https://savannah.gnu.org/bugs/?63034.
Indirectly-reported-by: Mike Scalora <mike@scalora.org>

Bug existed since before version 2.0.0.
