[feature-request] optional duration for temporary

[Kieren MacMillan]

Hello all,

Rather than having to \revert an \override (or set of \override-s), might it be 
possible to set an optional duration for which the override would be in effect? 
e.g.

  \temporary #’(10 1/8) \override LyricText.extra-offset = #’(0 . -1)

would lower the LyricText(s) for exactly 10 measures and 1 eighth note after 
the command was issued.

Just a “would be nice”.

Thanks!
Kieren.
