That can be added.

Those tags which scale their value needs some work. That is what the
TOKEN_VALUE_ONLY value is for. The point for that value is so those
scaled tags dont do any scaling at all, so battery level (when limit
== TOKEN_VALUE_ONLY) would always be between 0 and 100. If you do want
to use scaling there then the optional 3rd param overrides that. (so
%xd(a, %bl) and %xd(a, %bl, 10) would give slightly different
behaviours. (NOTE> this isnt being done yet though but is on my todo

well, yes and no. the debug output hasnt been fixed up since moving to
the new parser. It needs some work stilll
