Sure... but for consistence you should be able to say:
$ ./john --list=subformats -form=dynamic_2*
or
$ ./john --list=format-details -form=dynamic_2*
They give wrong outputs in different ways. I'd expect to get the list but only for the subset of dynamic_2, dynamic_20, 21 and so on. This doesn't work because dynamic has it's own "register all" that is not currently handling wildcards. Looks a little tricky to me, with scanf for "%d" and stuff. Would you like to have a shot or should I try to come up with a fix?
For non-dynamic formats like this:
$ ./john --list=format-details -form=hmac*
...it's handled by john_register_all(), which actually only registers the matching formats. This means we can use it not only to *list* particular formats but also to only try to auto-recognize (bare) hashes using formats that match the wildcard.
