[PATCH 023/177] man/curs_attr.3x: Drop erroneous/redundant material.

[G. Branden Robinson]

* Drop claim about non-meaningful return values.  There's no problem
  using a function-like macro in place of a function call.  If the
  function has a return value (`wattr_on` and `wattr_off`) or ultimately
  expands to `OK` or `ERR` (themselves object-like macros), there's no
  particular barrier to using them like function calls--you merely can't
  take their addresses.  (Am I missing something?)
* Drop claim about SVr4 man page, already discussed in "PORTABILITY"
  section.

-The return values of many of these routines are not meaningful (they are
-implemented as macro-expanded assignments and simply return their argument).
-The SVr4 manual page claims (falsely) that these routines always return
