Dynamics and articulation in lyrics

[Graham King]

I'm setting a song with multiple stanzas, in which I would like to include dynamics and articulations (breathing, phrasing) within the text.  After much hunting around the docs and snippets, I've got this far:

>     /version "2.19.2"
>     ...
>     secondverse = \lyricmode {
>         \set stanza = #"2."
>         \markup { \dynamic mf } Re -- mem -- ber me, a -- lace,
>         \markup { \musicglyph #"scripts.tickmark" }
>         And lat all rig -- our pass
>         \markup { \musicglyph #"scripts.tickmark" }
>         That I may prove in you some love
>         \markup { \musicglyph #"ties.lyric.default" }
>         To my joy and so -- lace
>         True love to move I most be -- hove
>         \markup { \dynamic p } Re -- mem -- ber me, a -- lace.
>     }
>     
but the dynamics and articulations are taking space in the lyric underlay as if they were syllables in their own right.

How should I solve this?

As a subsidiary question: Verses 4 & 5 of this song are set beneath the score as markup columns.  I'd like to do something similar in those verse also.
