Or, for that matter, easily
* put an arbitrary number of ">" in front, i.e. quote to a level.
* remove an arbitrary number of ">" in front, i.e. unquote
Fortunately, it seems that, in emacs as in perl, TMTOWTDI:

The way I find more obvious is to set ">" to be the comment character in
the mode you're using for editing. You can do that various ways, e.g.
(I'm sure there are others)
* with the sequence [M-x set-variable, comment-start, ">"]. Note the
need to enter the quotes literally.
* set as a local variable in a file, e.g. append the text
> Local Variables:
> Mode:text
> comment-start:">"
The advantage of this approach is, when one wants to quote a region,
one thinks of quoting as commenting, and just does comment-region
(bound, perhaps by default, to M-#). This means also that
* unquoting == C-u M-#
* quote to level=n == C-u n M-#
