[git] Remove directory from remote repository after adding them to .gitignore

This method applies the standard .gitignore behavior, and does not require manually specifying the files that need to be ignored.

Can't use --exclude-from=.gitignore anymore :/ - Here's the updated method:

General advice: start with a clean repo - everything committed, nothing pending in working directory or index, and make a backup!

#commit up-to-date .gitignore (if not already existing)
#this command must be run on each branch
git add .gitignore
git commit -m "Create .gitignore"

#apply standard git ignore behavior only to current index, not working directory (--cached)
#if this command returns nothing, ensure /.git/info/exclude AND/OR .gitignore exist
#this command must be run on each branch
git ls-files -z --ignored --exclude-standard | xargs -0 git rm --cached

#optionally add anything to the index that was previously ignored but now shouldn't be:
git add *

#commit again
#optionally use the --amend flag to merge this commit with the previous one instead of creating 2 commits.

git commit -m "re-applied modified .gitignore"

#other devs who pull after this commit is pushed will see the  newly-.gitignored files DELETED

If you also need to purge the newly-ignored files from the branch's commit history or if you don't want the newly-ignored files to be deleted from future pulls, see this answer.
