Files not ignored when linting from standard input

[christoph-blessing]

The ignore-patterns option can be used to ignore certain files based on the specified pattern. For example:

echo "def somefunc():\n    pass" > file.py; pylint --ignore-patterns 'file\.py' file.py

Here there would be no output because the input is ignored. This does not work when reading the input from standard in instead of from a file. This is problematic when using pylint as an on-the-fly linter (e.g. in vim) because there is no good way to ignore certain inputs.

Steps to reproduce

echo "def somefunc():\n    pass" | pylint --ignore-patterns 'file\.py' --from-stdin file.py

Current behavior

Input is linted.

Expected behavior

Input is ignored.

@Pierre-Sassoulas Well I tried fixing this but had problems with the implementation, which I unfortunately didn't report here. Now I no longer know what the problems were :-/
