This seems related:

http://lintian.debian.org/tags/rc-version-greater-than-expected-version.html

Should the RC tags in the Git repo be named v1.2.3~rc4 (tilde-rc#)
instead of dash-rc#, or does that not matter?

If so, would that change anything about this patch, or is it better to
normalize it all here?

The input is subtly different sometimes so I'm curious whether whether
"~" is preferred in all cases (particularly, by all package managers).
 e.g.

$ git describe v1.5.0^
v1.5.0-rc4-372-g26cfcfb

$ git describe v1.5.0.1^
v1.5.0-27-g38eb932
