I was thinking about this after #1935, but idk if it's a bug or just imprecise documentation.

These commands

mkdir -p /tmp/hidden/asd/
echo 'https://a.com/' > /tmp/hidden/asd/.a.md
cargo run -q -- --dump  '/tmp/hidden/**/*' 

will print

https://a.com/

The view could be taken that the glob specifies that the file should be included. Alternatively, a view could be taken that shell globs would exclude hidden files by default and we should do the same.

Maybe this is not a big issue.
