No, because the Theory file does not consider digits to be benign. 
Because the behavior of a TZ setting like "PST8" is specified by POSIX, 
it's problematic to use 'zic' to define a zone name like that.

I thought it'd help GNU Emacs indent it.  But it can be reworded to 
avoid that; I plan to do that as part of my next proposed patch.
