.gitignore issue

Hello,

I found an unexplainable behavior - see below.

best regards, Alf

Thank you for filling out a Git bug report! Please answer the following questions to help us understand your issue.

What did you do before the bug happened? (Steps to reproduce your issue) Adding an new line to .gitignore to filter directories.

What did you expect to happen? (Expected behavior) I expected to see no backup_STOCKS* directory on git status.

What happened instead? (Actual behavior) It also surpressed the backup/ directory.

What's different between what you expected and what actually happened? When I surpress backup_STOCKS* or backup_STOCKS*/ I expect a backup/ directory still to be visible.

Anything else you want to add: Here are the actions:

$ git status On branch master Your branch is up to date with 'origin/master'.
