Now exported. * stdio/linewrap.c (struct data): Type deleted (moved to linewrap.h). (wrap_stream, unwrap_stream, lwclose, lwfileno, lwoutput, line_wrap_stream, line_unwrap_stream): Use struct line_wrap_data instead of struct data. (lwoutput, line_wrap_stream, line_unwrap_stream): Rename various occurences of `wrap' and `wrapmargin' to `wmargin'. (line_wrapped, line_wrap_lmargin, line_wrap_set_lmargin, line_wrap_rmargin, line_wrap_set_rmargin, line_wrap_wmargin, line_wrap_set_wmargin, line_wrap_point): New functions. * stdio/linewrap.h: New file. * stdio/Makefile (headers): Add linewrap.h.
