Since we already assume Python >= 2.7, modernize this example to make it
work also on Python 3:
- use print() as function
- sort the mount points using a key for sorted(), instead of a
comparison function
- remove extra newline escape
- reident two lines according to the PEP 8 style
Add (after comma) or remove (before opening round bracket, and around
'=' in arguments) whitespaces according to the PEP 8 specification.
This is just code reformatting, with no behaviour changes; no content
changed beside whitespaces, so "git diff -w" gives an empty diff.
In libguestfs 1.20, you will be able to use 'add_drive'
instead of 'add_drive_opts' (except in the C bindings).
However until libguestfs 1.20 is the minimum stable version
people will still be using old versions where you have to use
'add_drive_opts'. This makes the examples confusing.
Therefore continue to use 'add_drive_opts' in the examples
for now.
By using the once_had_no_optargs flag, this change is backwards
compatible for callers (except Haskell, PHP and GObject as discussed
in earlier commit).
Fix guestfish (and other C tools) so that they ignore errors
when /etc/fstab contains bogus entries.
Update the documentation for inspect-get-mountpoints to emphasize
that callers must be aware of this when mounting the returned
values.
Add a regression test.
Update the example code ("inspect_vm") to reflect the way this
API ought to be called.
