Merge linewrap changes
Wed Jul 17 11:29:26 1996 Miles Bader <miles@gnu.ai.mit.edu>
* stdio/linewrap.c (lwupdate): Fix boundary condition where a
word extends right up to rmargin.
* stdio/linewrap.c (lwupdate): When we've done a word wrap and
output the wrap margin, set point_col to wmargin.
Use negative point_col to deal with a wmargin of 0.
(line_wrap_point): Return 0 for a negative point_col.
(line_wrap_stream): Make wmargin ssize_t.
* stdio/linewrap.h (struct line_wrap_data): Make wmargin &
point_col ssize_t.
(line_wrap_stream): Make wmargin ssize_t.
(line_wrap_point): Return 0 for a negative point_col.
Tue Jul 16 00:18:19 1996 Miles Bader <miles@gnu.ai.mit.edu>
* stdio/linewrap.c (__line_wrap_update): Add hackery from flshfp
to fiddle __put_limit in conjunction with __linebuf_active.
