Thanks; I share the same feeling. So after checking git://repo.or.cz/git-gui.git/ and seeing that I am not missing any commit from there, I tentatively created a fork of it, applied your patch and merged it somewhere on 'pu' that is close to 'next'. We may want to fast-track it to 2.0 without waiting for an Ack from Pat but let's give him one more day to respond. The analysis about the major version number being significant is correct. By default vsatisfies assumes that a major version number change means all lesser versions are incompatible. However, you can prevent that assumption using an unlimited check by appending a - (minus sign) to the version to yield an open ended range. Or by giving another range. So the only change required is to append a minus. package vsatisfies $::_git_version 1.7.0- will suffice. package vsatisfies $::_git_version 1.7.0 2.0.0 would work but would cause failures when we arrive at git 3.0 -- Pat Thoytshttp://www.patthoyts.tk/ PGP fingerprint 2C 6E 98 07 2C 59 C8 97 10 CE 11 E6 04 E0 B9 DD -- To unsubscribe from this list: send the line unsubscribe git in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
