* Parse arguments and parameters of macros. Arguments follow the |

* syntax of `-arg [val [valN...]]', while parameters are free-form text |
* of `-arg [val [valN...]]'. Arguments come in all types: quoted |
* following arguments (if any). This file must correctly handle the |
* arguments, multiple arguments per value, no-value arguments, etc. |
* strange punctuation rules dictated by groff. |
