Checking command line option typos

[szepeviktor]

Hello!
I'm a happy user of codespell. Including codespell in CI setups I contribute to open-source projects.

#     -m recent --update --seconds 600 --hitcount 6 --name SSHide --rsource \

There is a comment in one of my fail2ban config files.
rsource is a misspelling included in data/dictionary.txt

How can it be found?
changing it to -- rsource causes it to be found.

BTW rsource is a valid iptables option

Could the word regex be the cause?

codespell/codespell_lib/_codespell.py

Line 31 in ea349a2

word_regex_def = "[\\w\\-'’`]+"

We need - to catch words such as auto-detect.

Perhaps the regex could be modified to not catch leading or trailing dashes. You may define an alternative regex using option -r.

I think regexp-based operation may ignore some misspellings.
Parsing code may work better https://github.com/crate-ci/typos
