When reading the BFD manual, I noticed text like this:
-- Function: bool bfd_close (bfd *abfd);
Close a BFD. If the BFD was open for writing, then pending
operations are completed and the file written out and closed. If
...
*Returns*
'TRUE' is returned if all is ok, otherwise 'FALSE'.
The *Returns*, like the *Synopsis* in the earlier patch, is
un-info-like. It's also used inconsistently.
This patch removes all the uses of the RETURNS word and removes it
entirely from the chew scripts. Now this example reads:
-- Function: bool bfd_close (bfd *abfd);
Close a BFD. If the BFD was open for writing, then pending
operations are completed and the file written out and closed. If
...
'TRUE' is returned if all is ok, otherwise 'FALSE'.
In a few cases I had to slightly reword the comment. There were also
a couple of cases where there was redundant text. In these cases I
just dropped the RETURNS copy.

* bfd.c, cache.c, compress.c, opncls.c: Remove RETURNS from
documentation comments.
* doc/doc.str, doc/proto.str (RETURNS): Remove.
When reading the BFD info manual, function definitions looked very
strange to me:
*Synopsis*
long bfd_get_mtime (bfd *abfd);
*Description*
Return the file modification time (as read from the file system, or from
the archive header for archive members).
The *Synopsis* and *Description* text in particular is very un-info-like.
To fix this, I tried removing the *Synopsis* text and having FUNCTION
use @deftypefn instead. However, this ended up requiring some new
state, because SYNOPSIS can appear without FUNCTION. This in turn
required "catstrif" (I considered adding FORTH-style if-else-then, but
in the end decided on an ad hoc approach).
After this the result looks like:
-- Function: long bfd_get_mtime (bfd *abfd);
Return the file modification time (as read from the file system, or
from the archive header for archive members).
This patch also reorders a few documentation comments to ensure that
SYNOPSIS comes before DESCRIPTION. This is the more common style and
is also now required by doc.str.

* syms.c (bfd_decode_symclass, bfd_is_undefined_symclass)
(bfd_symbol_info): Reorder documentation comment.
* doc/doc.str (synopsis_seen): New variable.
(SYNOPSIS): Set synopsis_seen. Emit @deftypefn.
(DESCRIPTION): Use synopsis_seen.
* doc/chew.c (catstrif): New function.
(main): Add catstrif intrinsic.
(compile): Recognize "variable" command.
The .str script files don't have copyright headers, but I think they
should. I used the same dates that chew.c uses, which I think makes
sense because these are inputs to chew.

* doc/doc.str, doc/proto.str: Add copyright header.
