My file is currently automatically generated by dh_shlibdeps, and says
"libargtable2 0 libargtable2-0". I realize that I should place any
version restrictions there, if I want them. The question is whether I
should just state the version at which the interface advance there, or
whether I should do some other version tricks?

In a nutshell - because then the information regarding which backwards
compatible interface to use is lost. I guess it's ok IF it is not
possible for a given interface version to be backwards compatible in
some versions but not in others.
