Windows: setting / retrieving keys with case differences

[sambtalcott]

I'm on Windows, R 4.4.2, keyring v1.3.2

It seems that key_set() and key_get() act unpredictably when the provided service parameter matches a stored value but with different casing.

Reproducible example:

library(keyring)
key_set_with_value("example", password = "pass1")
key_get("example")
# [1] "pass1"

key_set_with_value("EXAMPLE", password = "pass2")
key_get("EXAMPLE")
# [1] "pass1"

Looking in the Windows Credential Manager after running this code, I only see the :example: credential (no :EXAMPLE:). If I remove the :example: credential, THEN I see an :EXAMPLE: credential appear (with password "pass2")

I'm not sure what's possible, but I think the expected behavior would be (in order of desirability):

1. Service is case-sensitive (so both "example" and "EXAMPLE" can be set/accessed separately). It seems like this may not be possible with Windows
2. Service is case-insensitive on both set and get (so setting "EXAMPLE" overwrites "example")
3. key_set() throws an error if attempting to set a credential that is a different casing of a currently stored value

I am afraid this'll be up to the windows credential store, which is case insensitive when doing comparisons, but keeps the case when you store a key. But I'll think about what we could do.

Oh, actually, you have a PR for this already, never mind then!
