Bug#682948: Incorrect versioning scheme disturbs upgrading

[IRIE Shinsuke]

I forgot to say that actually there were official deb packages using
"+cvs" suffix in the past (ex. 2.25b+cvs.2003.02.17-1).  So, "+svn"
suffix might be used for the future versions of the official packages.

I mean the versioning scheme like 2.63.1 is generally necessary,
not only for my PPA's packages.
