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.
