#62 Provide a SET INTERCEPT command

[LesK]

A SET INTERCEPT command could be of the form:

SET INTERCEPT cmd_or_macro_name intercepting_macro_name
SET INTERCEPT ON | OFF | DELETE [cmd or macro name]

This would allow an intercepting macro to examine the invoking command or macro string irrespective of the origin, which should be indicated: CMDLINE, Fkey, program_name, etc. and take some pre/post/ignore action. The
intercepting macro would need a special command to bypass further intercepting.

Associated QUERY/EXTRACT would be needed, of course.

An alternative name might be TRAP.
