Aw oh.   I slept on it and woke up thinking about this as my first conscious waking
thoughts this morning.  (Don't say it, I know I need to get a life, I've been working on
that, for a loooong time.)

As I attempt to show, I think there are some improvements in conciseness possible
(conciseness = ratio of clarity to size), even in the copper layer naming.

I like the wildcard notion and wanted to be able to use it in a few other places.  I also
noticed that "Inner3" does not explicitly say it is a copper layer.

Of course the value of the combos is the reduction in Pcbnew data file size, and increased
speed of parsing.  (Would put the [combo] mask into the hashtable instead of the layer index.)

Attached is my proposal and recommendation.

I would say that the combos can be used even in *.kicad_pcb files where they can.  Custom
layer names pertain to cu layers, and to tracks more than pads.  Here are the heuristics:

a) if a combo can be recognized in a layerMask when Format()ing, then it should be used,
in either BOARDs or MODULEs.

b) otherwise, if saving a BOARD, then use the translated layer names.

c) otherwise, if saving a MODULE, then use the untranslated english layer names.

Your proposal makes sense to me. I like the use of the wildcard search pattern to indicate multiple layers. You might consider renaming *.SoldP to *.Paste for the solder paste layer if your going to use *.Mask for the solder mask layer. It's a bit more consistent and solder is also implied in the case of *.Paste.
