"extension" option and config parameter doesn't override defaults

[nega0]

I don't want to check .rst or .txt files, only .bar files.

Given:

$ ls
foo.bar         foo.baz         foo.rst         foo.txt

running doc8 gives:

$ doc8 -v -e .bar .
Scanning...
  Selecting './foo.bar'
  Selecting './foo.txt'
  Selecting './foo.rst'
---8<---

The same behavior occurs when using a config file. In my case, pyproject.toml. This was suprising as one would expect that setting an option would override that option's defaults.

Obviously one could work around this using shell expansion (doc8 **/*.rst), and thats ok for command line use. But, my ultimate goal is to control doc8 via config file like I do with other tooling, and doing:

[tool.doc8]
ignore-path = [
"*.txt",
"*/*.txt",
"*/*/*.txt",
"*/*/*/*.txt",
"*/*/*/*/*.txt",
"*/*/*/*/*/*.txt",
]

is just inelegant.

As an aside, while taking a quick poke with pdb, it doesn't appear that any normalization/de-duplication happens when merging the "extension" setting. Maybe it happens later? 🤷
