I believe a block cannot contain -just- comments
or be empty, like this:
... {
# commented for
now
# discard;
}
but this might be the intention. If not,
these rules prevent this:
block = "{" commands "}"
commands = *([WSP]
command [WSP])
command = identifier
...
Maybe
commands = *[WSP] *([WSP] command [WSP])
although this does not
really reprsent commands.
