Cannot negate `*` ignore pattern for directory with space in the name

Cannot negate `*` ignore pattern for directory with space in the name

[Victor Engmark]

To reproduce (from <https://unix.stackexchange.com/q/469708/3645>):

$ cd "$(mktemp --directory)"
$ mkdir foo\ bar
$ touch foo\ bar/test
$ git init
Initialized empty Git repository in /tmp/tmp.iGmBR6y2xR/.git/
$ git status --short
?? foo bar/
$ cat > .gitignore << EOF
> *
> !foo bar
> !foo\ bar
> !"foo bar"
> "!foo bar"
> !foo*
> !foo bar/
> !foo\ bar/
> !"foo bar/"
> "!foo bar/"
> !foo*/
> EOF
$ git status --short
[no output]

The pattern *can* be negated if it only matches directories:

$ cat > .gitignore << EOF
> */
> !foo\ bar/
> EOF
$ git status --short
?? .gitignore
?? foo bar/

I encountered this problem because Visual Studio Code creates a
configuration directory called "Code - OSS", and I exclude everything in
~/.config by default to avoid noise in `git status`.

$ git --version
git version 2.19.0

No need to quote, either with double quotes or backslashes. They are
interpreted as literal " and \

It's not exactly a bug, more like a trap. '*' matches anything, at
every level. So even if you negate 'foo bar', when we check 'foo
bar/test', '*' pattern applies again and ignores 'foo bar/test'. If
the first line in .gitignore is /* instead of * (to keep match
anything at the top level directory only), then it should work.

Thanks! I just tried a bunch of things to see if anything stuck.

You're right, I've managed to induce the placebo effect in myself :)
Thank you for the help, and sorry for the noise!
