Your commit message lines are very long, format them to 80 columns
or less.

You're corrupted the indentation.
The second line of this while statement should start precisely at
the first column after the openning parenthesis of the first line.
You must use the appropriate number of TAB then SPACE characters
necessary to achieve this.
If you are purely using TAB characters, as you have done here, for
indentation then it is very likely that you have indented things
incorrectly.
