That's wrong. We prefer a space between the function name and the
parentheses for shell script, see:

The indent your made is ugly.

Code style of the original is goold, yours is bad. See:

 * https://github.com/git/git/blob/master/Documentation/CodingGuidelines#L100

This is the place you can fix by adding a space between the function
name and the parentheses.

Too deep indent. The original implementation is good, yours is bad.

Bad coding style, please read through the "CodingGuidelines" for bash.
