has a strange output imo

Slight problem: The patching level usually is not indicated by a number
but by "p" plus a number. So, providing the version as a list of integers
is perhaps not what we want. And it is not good, I think, if the default
output is a list of integers and the verbose output is a totally different
type, namely a string.
From that perspective, the r-output is better.
> Maybe this could also be documented in
http://doc.sagemath.org/html/en/developer/packaging.html#package-
versioning as the recommended way to have `*.version()` commands?
I didn't know about the existence of a `package_version.txt`. I wonder if
we could access these data---after all, the package version of singular is
"3.1.7p1.p0", but the version shown by
`singular.eval('system("version")')` is "3170". Similarly for r, it should
be `3.2.1.p0`, not `(3,2,1)`.
I guess it is time to do a bit bike shedding at sage-devel.
