Subject: zone.lisp: Refactor and improve the domain-name sorting.
X-Git-Url: https://git.distorted.org.uk/~mdw/zone/commitdiff_plain/05e83012402ab4231225d00f937924272924fb4b?hp=05e83012402ab4231225d00f937924272924fb4b

zone.lisp: Refactor and improve the domain-name sorting.

Sort the components according to a `natural' ordering which tries to do
approximately sane things with numeric sequences.  It's not always
successful: in particular, it wants to order 144, 144-159, 145, ...; but
it's not too awful.
