Scripts: differentiating in overrides

[Simon Albrecht]

Hello everybody,

it happens that just now Joe Srednicki asked about colouring _only_ 
organ pedal markings as a subset of scripts, which is most cleanly 
solved by redefining the keywords ltoe etc. including a tweak. Today I 
needed to \tweak avoid-slur #'inside for tenuto -- but not for accents 
->, which I did by a temporarily overriding Script’s property, which is 
only satisfactory if the don’t appear both on one note, don’t alternate 
a lot, and in short pieces.

So, it clearly seems to be a desideratum to have a facility of 
distinguishing all the different uses of Script in overrides. Do you 
have any idea how that may be achieved in a clever way? Creating 
separate grobs for all of them would of course be a huge clutter, and a 
quite disruptive change.

Best, Simon
