Adding a commit message with a brief description of what this patch does would be great. Also add a line with the number of the bug it fixes. I do not like --dont-downgrade because of the "dont". Abbreviations should be avoided. I'm also not a fan of "--no-downgrade" How about "--prevent-downgrades" and adding a short option? "-p" or "-d" would work. Otherwise, happy with the patch. Quoting the arguments to vercmp would not hurt. Thanks, Allan
