    parser: Fix backquote support in here-document EOF mark

    Currently using backquotes in a here-document EOF mark is broken
    because dash tries to do command substitution on it.  This patch
    fixes it by checking whether we're looking for an EOF mark during
    tokenisation.

With added fix for quoted-ness of the EOF mark.
