I've noticed a bug in the "autowidth" feature more, and is probably in
others. The call to the function get_terminal_width_height() passes
in a file descriptor but that file descriptor is never used, instead
the ioctl() is called with 0. In more_main() the call to
get_terminal_width_height() passes 0 as the file descriptor instead of
fileno(cin). This isn't a problem when you more a file (e.g. "more
/etc/passwd") but when you pipe a file to it (e.g. "cat /etc/passwd |
more") the size of the terminal cannot be determined because file
descriptor 0 is not a terminal. The fix is simple, I've attached a
patch for more.c and get_terminal_width_height.c.
