Python-augeas

- restore the behavior of aug_save; in 0.3.2, aug_save broke API by
returning the number of files changed on success instead of 0

- saving now reports which files were actually changed in
/augeas/events/saved; aug_save also returns the number of files
that were changed
- preserve file owner, permissions and SELinux context when changing a file.
- make saving idempotent, i.e. when a change to the tree does not result
in changes to the actual file's content, do not touch the original file
- report an error if there are nodes in the tree with a label that
is not allowed by the lens
- quietly append a newline to files that do not have one
- generate lens documentation using NaturalDocs and publish those
on the Auegas website (Raphael Pinson)
- Lens changes/additions
* Grub: support the 'password' directive (Joel Nimety)
* Grub: support 'serial' and 'terminal' directives (Sean E. Millichamp)
* Samba: change default indentation and separators (Free Ekanayaka)
* Logrotate: process tabooext, add dateext flag (Sean E. Millichamp)
* Sshd: Cleaner handling of 'Match' blocks (Dominique Dumont)
* Monit: new lens (Free Ekanayaka)
* Ldap: merge with Spacevars (Free Ekanayaka)
* Shellvars: support /etc/default (Free Ekanayaka)
* Shellvars: handle space at the end of a line

- Major performance improvement when processing huge files, reducing some
O(n^2) behavior to O(n) behavior. It's now entirely feasible to
manipulate for example /etc/hosts files with 65k lines
- Handle character escapes '\x' in regular expressions in compliance with
Posix ERE
- aug_mv: fix bug when moving at the root level
- Fix endless loop when using a mixed-case module name like MyMod.lns
- Typecheck del lens: for 'del RE STR', STR must match RE
- Properly typecheck the '?' operator, especially the atype; also allow
'?' to be applied to lenses that contain only 'store', and do not
produce tree nodes.
- Many new/improved lenses

deleting them

at the end of a line (Kjetil Homme)
