[BUG] ignored option does not pretend the file doesn't exist

[dcastro]

Description

( Original conversation, see the comments in #118 )

The help text for the --ignored option in xrefcheck --help says the following:

Files which we pretend do not exist.

However, this doesn't seem to be true. We do not pretend they don't exist. If a link references that file, we do in fact check that it exists.

To Reproduce

mkdir demo && cd demo
echo "[](b.md)" > a.md
touch b.md

$ xrefcheck --ignored b.md
All repository links are valid.

Expected behavior

Expected xrefcheck to pretend b.md doesn't exist, and report an error in the reference from the a.md file.
