Subject: [PATCH] Add an error message for catching a common failure mode.
If you're in a directory that has a parent .gitignore (like, your $HOME),
then it can cause ripgrep to simply not do anything depending on your
ignore rules.
There are probably other scenarios where ripgrep applies some filter that
an end user doesn't expect, so try to catch the worst case (when ripgrep
doesn't search anything).
