Adding option to select file types

[lisa-asket]

Why does printf complain with the following help displays?



        frmt="%s"
        printf $frmt "Print text surrounding line numbers from named files.\n"
        printf $frmt "-d DIR\n--directory=DIR\n"
        printf $frmt "    Directory.\n"
        printf $frmt "-e TYPE\n--extension=TYPE\n"
        printf $frmt "    Extension defining file type.  Multiple file are\n"
        printf $frmt "    separated by a comma (e.g. `-e org,texi`).\n"
        printf $frmt "-p NUM\n--startline=NUM.\n"
        printf $frmt "    Start line number.\n"
        printf $frmt "-q NUM\n--stopline=NUM.\n"
        printf $frmt "    Stop line number.\n"

One probably should check if "$dir" starts with a "-" (and prepend ./ if so)?
