case-sensitive Ignore

[dkg]

I'm looking at a document `foo.txt that mentions someone named "William Manger".

codespell defaults to thinking that "Manger" should be "Manager"

If i invoke codespell --ignore-words-list Manger foo.txt it still suggests the correction, presumably because the codespell rule is manger->manager.

It would be nice to be able to ignore Manger while still letting codespell catch manger.

dkg@alice:~$ cat test.txt
William Manger is the project
manger in charge of excellence.
dkg@alice:~$ codespell test.txt 
test.txt:1: Manger ==> Manager
test.txt:2: manger ==> manager
dkg@alice:~$ codespell --ignore-words-list Manger test.txt 
test.txt:1: Manger ==> Manager
test.txt:2: manger ==> manager
dkg@alice:~$ codespell --ignore-words-list manger test.txt 
dkg@alice:~$ 

It would be nice if instead we got this:

dkg@alice:~$ codespell --ignore-words-list Manger test.txt 
test.txt:2: manger ==> manager
dkg@alice:~$

I think this would only want to be an option at most. e.g. there's a protocol called ACN which some code I'm involved in supports, obviously that might exist in the codebase as both ACN and acn, so I just want to skip acn->can regardless of case.

I suspect the reality is this probably wants to be on a per-word basis, as mentioned elsewhere, adding that sort of thing to the ignore list gets complicated as you have to be able to escape them, but having say --ignore-words-list and --ignore-words-list-case-sensitive might be the solution perhaps...
