/* Find the next text line.

   This routine scans the text provided buffer until it encounters
   either a linefeed (\\n) or a null byte (\\0). If it finds a line
   feed, it returns a pointer to the *next* line. If it finds a null
   byte, a pointer to that null byte is returned.

   Using this routine you can easily scan a text buffer line for line,
   just use a look like this:

     while((p = text_find_next_line(p)) != '\\0') ...
