Because of previous automated commits, such as changing 'guestfs___' -> 'guestfs_int_', several function calls no longer lined up with their parameters, and some lines were too long. The bulk of this commit was done using emacs batch mode and the technique described here: http://www.cslab.pepperdine.edu/warford/BatchIndentationEmacs.html The changes suggested by emacs were then reviewed by hand.
