Better argument display in autodoc
Simpler (we don't need no square brackets) and more correct (keywords display as keywords and we only include default values when available (Guile, i'm looking at you).

some explanation. It will first show the name of the module where the
identifier at hand is defined, followed by a colon and the identifier
itself. If the latter corresponds to a procedure or macro, it will be
followed by a list of argument names, starting with the ones that are
-required. Then there comes a square-bracketed list of optional argument
-names, if any. When an optional argument has a default value (or a form
-defining its default value), instead of a plain name, autodoc will
-display a list with the name followed by its initialisation form. When
-the optional arguments are keywords, their names are prefixed with a
-colon. An ellipsis (@dots{}) servers as a marker of an indeterminated
-number of parameters, as is the case with @i{rest} arguments or when

@img{autodoc-multi, right} It can also be the case that a function or
macro has more than one signature (e.g., functions defined using
@code{case-lambda}, or some @code{syntax-rules} macros, for which Geiser
has often the black magic necessary to retrieve their actual arities).
In those cases, autodoc shows all known signatures (using the above
