Hi Colin,

I see three bugs

(1)
The markup-commands \note-by-number and \note don't support other
flag-styles than default.

This will result in ugly output.
I'd consider this of type: enhancment.

Example:

\version "2.17.9"

\markup {
        \override #'(style . mensural)
        {
                \note-by-number #3 #0 #1
                \note #"8" #1
        }
}

(2)
`format-metronome-markup' and `metronome-markup' from
/scm/translation-functions.scm don't support other note/flag-styles
than default.
(Even if \note-by-number would support them.)

(Can't imagine an example)

This is part of the problem Karol reported initially.
I'd consider this of type: enhancment.

(3)
In mensural-style the stem and flag aren't well combined.

Example:

\version "2.17.9"

{
 \override Flag.style = #'mensural
 \override Stem.thickness = #1.0
 \override NoteHead.style = #'mensural
 c'8
}

I'd consider this of type ugly.
