#1256 added a support for lone short flag.

Unfortunately, this only works correctly on short flags with one character. Short flags with multiple characters (Java-style short flags) will incorrectly create incorrect field names. For example, .option('-name') will result in a field Name, which is not in camelCase.

The reason is that this regex only matches a short flag with one character. This means a short flag with multiple characters will be categorized as a long flag. Consequently, Commander.js attempts to strip -- from -name, which is a no-op, resulting in -name. Then, the camel case conversion of -name results in Name, which is not a camel case as intended.
