[PATCH] rpmbuild doesn't like '-' in version strings

[John Ellson <ellson@research.att.com>]

Problem:

	ellson@ellson:git> make rpm
	GIT_VERSION = 1.0.6-g58e3
	sed -e 's/@@VERSION@@/1.0.6-g58e3/g' < git.spec.in > git.spec
	./git-tar-tree HEAD git-1.0.6-g58e3 > git-1.0.6-g58e3.tar
	tar rf git-1.0.6-g58e3.tar git-1.0.6-g58e3/git.spec
	gzip -f -9 git-1.0.6-g58e3.tar
	rpmbuild -ta git-1.0.6-g58e3.tar.gz
	error: line 3: Illegal char '-' in version: Version:    1.0.6-g58e3
	make: *** [rpm] Error 1


Suggested fix:  Use '_' instead of '-'

There is probably a cleaner implementation of the fix, but this works for me.
