`n' is the easiest key to press, so it should perform navigation that 
the users will find most useful, in general.

If the behavior does not correspond to the command name, it would be 
better to rename the command, or change its docstring, or etc.

But I don't think `diff-hunk-next' jumping to the beginning of the first 
hunk when invoked at the file header, is in any way odd. After all, 
point wasn't inside a hunk before.

Note, however, that nobody else has stepped forward to explicitly 
support the new behavior.

If you get around to polling Emacs users at your workplace, or a meetup, 
or so on, please let us know.
