That wouldn't let a user have the skip_chars=0 beahaviour for a wider
context and the "act like the builtin" behaviour for a more specific
subcontext. (It's not possible to unset for a subcontext a style that's
set on a wider context.)
How about changing the pattern from «*» to «<->»? Then a setting on
a wider context can be hidden for a subcontext by setting the style to
'' on the subcontext.
Cheers,
