Subject: simplified "lexer.test..." macros using the $$ return command

 * this is slightly more efficient than using repeated conditionals
 * the last :EN does not require a conditional, as its return
   value can simply be forwarded.
 * even without $$, this could have been done easier using
   a once-only loop and breaking out of the loop if :EN fails using :;.
   The last :EN result is still stored in QReg "_".
 * :EN could also be used to match header lines if lexer.tes would
   leave the first line (header line) in some Q-Reg, like the local
   .[header].
   However, repeated :ENs would be necessary as globbing currently
   does not support {...,...} expansions.
   Since sooner or later, the header line must be evaluated for some
   lexer.set macro, this is probably more efficient than the current
   solution using SciTECO patterns and [lexer.checkheader] could be removed
   as well.
