All package managers I investigated do handle ~ specially, and thus
recommend it for rc versioning, except pacman. So in pacman,
v1.5.0~rc4 would remain newer than v1.5.0, but that's not different
from the current situation, and there isn't much we can do about that.

At least both in RPM and dpkg, 1.5.0~27 is newer than 1.5.0~rc4.
