* parser.l: Bugfix. When handling a backslash-newline continuation

in the SPECIAL, NESTED and BRACED states, do not pop the state in all
three, only in SPECIAL (to terminate the @\ continuation).

* txr.1: Eliminate wrong claim that string literals do not split across lines,
which is directly contradicted two paragraphs later.  Document that
quasiliterals also split.

* genvim.txr (txr_regex, txl_regex): These definitions change from "syn match"
to "syn region" so that the backslash-newline continuation can be properly
handled.
(txr_string, txr_quasilit): Correctly handle split literals.

* txr.vim: Regenerated.
