It's not Red Hat's convention, it's RPM, and dpkg, so basically every
package manager that most distributions out there use.

And I already sent a patch for that which was ignored:

That wouldn't work; VERSION doesn't have '-rc', it has '.rc'. and
what's the point of creating a new variable? It's a was of space.

Do you have any evidence that such programs exist? Specifically,
programs that work with 1.8.4.rc1, but not 1.8.4-rc1 or 1.8.4~rc1. I
find that very very very unlikely.

Anyway, in the very very very unlikely scenario that somebody's script
does break they can report that, and we can revert. What's the

It doesn't matter. The name of the package would be git-1.8.4~rc1, and
'git --version' would return 1.8.4.rc1, that's inconsistent.

Why be inconsistent when we can be consistent?

Because a) they don't package release candidates, and b) they use a
different version (s/\./~/).
