templates/quote: only prefix quoted lines with '>'

Prefix all quoted lines with depth > 1 with '>'. Quoted lines of depth 1
are quoted with "> ". This follows conventions of mailing lists which
collapse quote depths without spaces. For example:

    >>> Quote depth 3
    > Quote depth 1
    >> Quote depth 2

Changelog-changed: Template function `quote` only prefixes with a
 space if at quote depth 1.
