.gitignore is whitespace sensitive?

My .gitignore file seems to be working unpredictably. Here is an example:

I make a new repo foo with a file bar.txt, which I want to ignore:

pon2@kann4:~$ mkdir foo
pon2@kann4:~$ cd foo/
pon2@kann4:~/foo$ touch bar.txt
pon2@kann4:~/foo$ git init
Initialized empty Git repository in /home/pon2/foo/.git/
pon2@kann4:~/foo$ git status
# On branch master
#
# Initial commit
#
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#       bar.txt
nothing added to commit but untracked files present (use "git add" to track)

As expected, bar.txt shows up as untracked. So I tell git to ignore .txts, but I accidentally add some trailing whitespace:

pon2@kann4:~/foo$ echo "*.txt " > .gitignore

Now when I check the repo status, git doesn't ignore bar.txt:

pon2@kann4:~/foo$ git status
# On branch master
#
# Initial commit
#
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#       .gitignore
#       bar.txt
nothing added to commit but untracked files present (use "git add" to track)

What's going on?

This changed in git 2.0. From the release notes:

Trailing whitespaces in .gitignore files, unless they are quoted for fnmatch(3), e.g. "path\ ", are warned and ignored. Strictly speaking, this is a backward-incompatible change, but very unlikely to bite any sane user and adjusting should be obvious and easy.

.gitignore is whitespace sensitive. If you include trailing whitespace, git won't recognize your files.

In this line there's a trailing space:

pon2@kann4:~/foo$ echo "*.txt " > .gitignore

Once we fix that:

pon2@kann4:~/foo$ echo "*.txt" > .gitignore

The issue resolves:

pon2@kann4:~/foo$ git status
# On branch master
#
# Initial commit
#
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#       .gitignore
nothing added to commit but untracked files present (use "git add" to track)
pon2@kann4:~/foo$
