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
