command line: --eargs semantics change.

The --eargs mechanism won't perform a blind substring
replacement of {} with the following argument. Only
arguments which match {} exactly are replaced.

* eval.c (retf): Static function becomes extern.

* eval.h (retf): Declared.

* txr.c (txr_main): Replace the filtering logic on the
split eargs argument list to just look for items
equal to the string "{}" and replace with the following
argument.

* txr.1: Updated --eargs documentation.
