Richard W.M. Jones 677c721e85 Fix whitespace.
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.
