Dictionary missing term when cased correctly

[blakev]

When using a dictionary file that contains the word I want ignored, cased correctly, codespell will not ignore it.

Contents of .dictionary:

ZUser

Command line output:

(app-service-link) [blake@bv-desktop app-service-link]$ codespell -S *.log -I .dictionary
./app/servicelink.py:23: ZUser ==> user
./app/servicelink.py:341: ZUser ==> user

However, if I change the case to zuser then it works as expected. This is contradictory to the help message for -I,

Words are case sensitive based on how they are written in the dictionary file

Using version 2.1.0 in Bash on Linux, normal text files with UTF8 encoding.

The usage section now says:

Important note: The list passed to -I is case-sensitive based on how it is listed in the codespell dictionaries.

We've had a few recent PRs to try and clarify this further, but please let us know if you've got any further suggestions to improve the wording of that help info.

The file you're using (despite what you happen to have named it), is an ignore words file, the dictionaries are in https://github.com/codespell-project/codespell/tree/master/codespell_lib/data and have the typo=>correction entries.
