Re; Unset prefer \revert

[Jay Hamilton]

I would hope that Mats' suggestion of \revert be instituted as that would make 
it follow some other \revert commands in consistency.  Our problem (Emily's and 
mine) was we were trying to find something that unset the set but there was 
nothing in the Docs.
However I did see (today finally) something about revert and didn't have time 
to try it, though it made the most sense.

Yours-
Jay

The documentation does state that \setEasyHeads overrides settings
for the NoteHead object, so that information could have been found
in the manual. However, you used a very advanced strategy to reset all 
local property settings on a particular object, which requires
good knowledge about the data representation used internally in 
LilyPond and isn't documented anywhere. I'm not sure if it's always
the best solution, though. For example, it means that any other 
property settings on the NoteHead objects will be lost as well, such as
\override NoteHead #'color = #red

I would rather have proposed to add a definition like
revertEasyHeads = \sequential {
  \revert NoteHead  #'stencil  \revert NoteHead #'font-size
  \revert NoteHead #'font-family  \revert NoteHead #'font-series }
into property-init.ly, which only reverts the particular settings
of \setEasyHeads and keeps all the rest.
