Subject: adns_str* etc.: Permit calling on adns_s_* values (not _max_)
X-Git-Tag: adns-1.6.0~5
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?p=adns.git;a=commitdiff_plain;h=ab9603b004ef2bfd1c3450b915320b45a07f58c8

adns_str* etc.: Permit calling on adns_s_* values (not _max_)

This is useful because otherwise an application may not use these
values for its own errors, if that might result in them being passed
to the adns_strerror etc.

No code change: the table already has all the values.
