CSpell should never be run against patch files
Problem/Motivation
Patch files, by design, contain parts of source from other files. This can cause spelling error to be reported in the patch file if the original file is ignored, either via cspell:disable, being included in _CSPELL_IGNORE_PATHS or it is one of the standard ignored files.
Proposed resolution
Do not run CSpell on any patch file.
Add something **/*.patch to the list of files that should never be checked.
