Exclude files efficiently

[pereorga]

I have this in .ecrc:

{
    "Exclude": [
        "docroot/img/",
...

However, I'm still getting thousands of messages when running npx ec --verbose:

Don't add docroot/img/XXXX.png to be checked.

It looks like ec is trying to loop for a directory of thousands of files, when it could avoid entering the directory in the first place. Not entering the directory could considerably decrease the time it takes the ec command to finish. Of course, the ec command can also be called in specific directories, but it is sometimes useful in a project to include all files by default, and just exclude some directories, so all new files and directories are checked by default.
