netdoc: Remove a TODO hs comment.
It said to check whether C enforces an absence of extraneous bytes
at the end of the link specifiers. It does, in
hs_desc.c:decode_link_specifiers()
, where it says:
if (link_specifier_list_parse(&specs, decoded,
(size_t) decoded_len) < decoded_len) {
goto err;
}
The comparison with "decoded_len" checks whether all the bytes were decoded.
