There's a minor issue with the new character class command ~e?C

The following 3 uses of the command works as expected:

echo p@ssW0rd | hashcat --stdout -j '~e?d'
P@ssw0Rd

echo p@ssW0rd | hashcat --stdout -j '~e?s'
P@Ssw0rd

echo p@ssWord | hashcat --stdout -j '~e?u' (I replaced 0 with o to emphazise the result)
P@ssWOrd

But with character class ?l:
echo p@ssW0rd | hashcat --stdout -j '~e?l'
P@ssW0rd

In the last case I would expect the following:
P@sSW0rD

With character class ?H:
echo abCDefGHij | hashcat --stdout -j '~e?H'
AbCDEfghij

Works ish', but used on a word that contains characters not in A-F, I would not expect it to lowercase them.
I would expect:
AbCDEfGHij

With character class ?h:
echo abCDefGHijKL | hashcat --stdout -j '~e?h'
AbCdefGhijkl

With ?h I would expect:
AbCDeFGHij

On https://hashcat.net/wiki/doku.php?id=rule_based_attack in the description of the command, it says:

Capitalize the rst letter and every letter following a character from class C

I suggest changing it to:

Capitalize the first letter and every first letter following a character from class C
