edoc: commenting multiple patterns of a function

[Vincent de Phily]

Hi list,

not a big issue but it always bugged me: how do you add edoc comments to a 
function depending on its pattern match ? eg:

-behavior(gen_server).
...
% @doc Modify counter.
handle_cast({inc, N}, Count) -> {noreply, Count + N};
% @doc Reset counter.
handle_cast(reset, Count) -> {noreply, 0};
handle_cast(Other, Count) -> {stop, {api_violation, Other}, 0}.

In this example, the edoc-generated file will just say "Modify counter", 
ignoring that the function can also "Reset counter".

What I hoped to find in the doc, was the two @doc comments, ideally with the 
corresponding pattern (it would be great if that pattern could be specified 
in the docs).

I could add all the documentation in the first @doc instance, but it'll be 
horribly unreadable (especially in a gen_server with numerous large handle_* 
functions).
Or I could use a generic "handles gen_server casts, see source for possible 
casts", but it makes the edoc a bit useless (I allready know what the 
behavior callbacks do, no need to read project-specific doc).

Any thoutghs ?
