use-symbolic-message-instead should be case-insensitive for numerical IDs

[Igetin]

Bug description

When use-symbolic-message-instead is enabled, Pylint will correctly warn about the usage of non-symbolic ID in pragmas, like here.

# pylint: disable=W0223

This will output I0023: 'W0223' is cryptic: use '# pylint: disable=abstract-method' instead (use-symbolic-message-instead).

But if the category letter of the ID is written in lower case, like here:

# pylint: disable=w0223

Pylint will not output the warning about not using a symbolic message.

Configuration

[MASTER]
enable=use-symbolic-message-instead

Command used

pylint test.py

Pylint output

No output.

Expected behavior

Since Pylint does allow lower case in the pragmas that use a numeric ID (e.g. w0223), having use-symbolic-message-instead enabled should also output a message regardless of the case of the ID used in the disable pragma.

Thank you for opening the issue, I can reproduce that. Strangely c0111 works but not w0223. Might be harder to troubleshoot than I thought.

[Pierre-Sassoulas]

It was due to C0111 being correctly capitalized once in the functional test I was using. It should be fixed in 2.11 :)
