There is a long-standing problem in Mutt, related to coloring the
various levels of quoting: if the attributions are missing, like
this:
        >>> blah blah from A
	>> blah blah from B
	> blah blah from C

then the "quoted" color object is associated with ">>>", "quoted1"
with ">>" and "quoted2" with ">" --- which is not what most people
expect. The reason is Mutt doesn't count the quote characters (since
there is no way to distinguish between a single quote ">> " and a
">" followed by a "> "), and it allocates colors as it finds new
types of quote prefixes. The attached patch fixes this problem still
without counting the quote characters.
