Fix typo in bash credentials helper example

[JoshuaBehrens]

Changes

There is a code example, that is not an executable example:

After the change it should look like this

Context

I am looking to implement a custom git credentials helper and did not find a good example. I am not sure though, whether the example shouldn't even be

! if("$1" == 'get') { echo "password=s3cre7"; };

The original is actually correct. It defines a shell function and then immediately executes it.

The code after the change is incorrect because it pretends that it's an if construct. But if constructs in shell don't take parentheses or empty conditionals, and it's not executed at all, it gives a syntax error, or at least it should.

In any case, this change would need to be made in the ProGit book repository, if it was correct, not in the git-scm.com repository.

Hi @dscho thank you for point it out. Must've been a misread that it looked like a misplaced copy-pasta and would've been an if. Thank you for the guidance and the helpful explanations! 👍 ❤️
