I think it would be nice if Octave's 'compare_versions' function supported the
special case sorting of the tilde ('~') character as defined by both the deb
and rpm package formats.
Under this definition, any suffix of a version string that starts with '~'
sorts strictly less than the same string with the suffix completely removed.
Any characters after the '~' sort normally. For example, "1.0.0+" is greater
than "1.0.0" simply because it adds a suffix. With this change made, "1.0.0~"
is less than "1.0.0". And "1.0.0~a" is greater than "1.0.0~"
I will raise this on the maintainers list as well to see if there are any
strong objections, but I hope it's non-controversial since it's already
supported by both deb and rpm packaging tools.
One risk is that making this change might break existing sorting if any
third-party code is using compare_versions and using the '~' character. No
Octave Forge packages currently use '~'.
