An example, > from t9001-send-email.37: This made me wonder if the warnings are new, or if the duplicated auto-negated options are new. I.e., were the manual "--no-foo" option specs doing something useful in the older versions (in which case we'd need to do something more complicated)? But I think the answer is no. We've explicitly marked these with "!" to indicate that they're negatable. And certainly running with Getopt::Long 2.52 (from perl 5.36, which is the current in Debian unstable) seems to support them. It does make me wonder why some boolean options are not marked as negatable (even if just to countermand an earlier option), but that is outside the scope of your patch. > I've run this through the full test suite.

But isn't "-h" just dumping a static usage message we wrote, and not auto-generated by the code? The changes look good to me (even after double-checking Junio's question that they are all appropriately matched with their "positive" sides). This one is curious: > - "cc-cover|cc-cover!" => \$cover_cc, It was an alternate name for itself? I think somebody just misunderstood how the API was supposed to work. The "!" would applies to all names, if I understand correctly, so this really is doing nothing beyond just "cc-cover!", which is what your patch switches it to. -Peff
