spelling-private-dict-file should be looked up relative to pylintrc file instead of current folder

[jjmortensen]

Bug description

With this in my pylintrc (which is at the root of my git repository):

[SPELLING]
spelling-dict=en_US
spelling-private-dict-file=doc/words.txt

pylint will only find the words.txt file if I'm launching it from the folder where the pylintrc file is.

Configuration

No response

Command used

pylint code.py

Expected behavior

It should find the words.txt file also when I'm in a subfolder of the folder where the pylintrc file is.

Thank you for opening the issue :)

I'm looking into it. I've started a hack using os.path.isabs but it's too hot to use a desktop computer at the moment so might as well design properly to make all configuration options that use paths better :) This might not be easy to fix generically because the args parsing is generic and we parse cli args with the same function than conf file args. For CLI the point of ref should be the python interpreter dir for config file it's the config file directory. We have an interface for this function with no way to give the relpath afaik. Do you have an opinion on how to tweak the path parser to handle both cases @DanielNoord ?
