Subject: [PATCH] Add link to appup manpage in release handling doc

Additionally, document that `UpFromVsn` and `DownToVsn` can also be a
regular expression (explained in detail in the `appup` reference): the
current document implies, to me, that previous versions must be a fixed
string, whilst the appup file can deal with regular expressions as well.
