[mkgmap-dev] default style lines enhancements

Hi Gerd

It can only be:
  ${tagname|filter:args}
or
  ${tagname|filter1:"arg with spaces"}

and, for the subst filter, the from=>to counts as a single arg.

In the example:
  ... '${ref|subst: =>} ${mkgmap:dest_hint|subst:;=> |subst:/=> }'
spaces are insignificant either side of the first | and before the :
but are significant after the : and before subsequent |.

The style manual says:
 If the argument contains spaces or symbols it should be quoted.
   For backward compatibility, most cases where you have spaces or
 symbols do not actually need to be quoted, however we would
 recommend that you do for clarity.  If you need a pipe symbol
 or a closing curly backet, then you must use quotes.
