Changes in version 2.55
-----------------------
* Fix long standing bug that duplicate options were not detected when
the options differ in case while ignore_case is in effect.
This will now yield a warning and become a fatal error in a future
release.
```
Current version is 2.57
```
git-2.43.0 🐧 perl -Iperl git-send-email.perl --help
Duplicate specification "cc-cover|cc-cover!" for option "cc-cover"
Duplicate specification "no-cc-cover" for option "no-cc-cover"
Duplicate specification "to-cover|to-cover!" for option "to-cover"
Duplicate specification "no-annotate" for option "no-annotate"
Duplicate specification "no-format-patch" for option "no-format-patch"
Duplicate specification "no-signed-off-cc|no-signed-off-by-cc" for option "no-signed-off-cc"
Duplicate specification "no-signed-off-cc|no-signed-off-by-cc" for option "no-signed-off-by-cc"
Duplicate specification "no-validate" for option "no-validate"
Duplicate specification "no-chain-reply-to" for option "no-chain-reply-to"
```
`"option!" => \$value`
*automatically* supports both `--option` and `--no-option` and `--nooption`
See the docs for Getopt::Long:
```
The argument specification can be
! The option does not take an argument and may be negated by
prefixing it with "no" or "no-". E.g. "foo!" will allow "--foo" (a
value of 1 will be assigned) as well as "--nofoo" and "--no-foo" (a
value of 0 will be assigned). If the option has aliases, this
applies to the aliases as well.
Using negation on a single letter option when bundling is in effect
is pointless and will result in a warning.
