I like this more: flags introduced by '-' since if a flag is not a
number there is no ambiguity with negative numbers (allowed for the
more builtin facility). So -p would mean pattern, -g use groups instead
of driver name and -pg apply a pattern to group names and even -s
meaning STARred (-pgs, letters in whatever order, meaning apply a
pattern to group names for STARred devices)...

And without flags, this is the present syntax untouched.

This will address too the legitimate concern of Staffan Thomén about
keyboard mapping: this adds less characters, and not special ones.

For variables, I will refrain for the moment because this will impose
to add a fraction of a page (1/4, 1/2 or 1/1) as scratch "memory" to
allocate and a simple allocation scheme (a la Unix version 6 for
example: see Lion's Commentary) in order to not allocate with kernel
facilities. Not difficult, not adding much but if not necessary...
