Content filtering has landed in bzr.dev

[Ian Clatworthy]

At long last, "content filtering" has landed in bzr.dev!
This feature is the basis for our EOL handling and keyword
expansion support. I'm sure it will find many more uses
as well.

I'd *greatly* appreciate it if users interested in these
features could find some time to assist with testing and
stabilising them. To do this, try downloading the bzr-eol
and bzr-keywords plugins, & giving them a go:

* https://launchpad.net/bzr-eol
* https://edge.launchpad.net/bzr-keywords

Note that I haven't touched these plugins for months so
they may need some minor tweaks to get them going. If
that's the case, please raise a bug and I'll take a look
as soon as I get a chance.

In particular, I'd like some assistance in expanding the
test suite for the bzr-eol plugin. As soon as this is
mature enough and making enough people happy, I think we
ought to make it a standard plugin so EOL support is
provided out-of-the-box.

If you're keen, please also try writing your own content
filter, e.g. for stripping trailing whitespace or some
other interesting application.

Finally, a big thanks to Alexander for getting the EOL
ball rolling many months ago. I'm sure he'll be smiling as
much as I am when the remaining pieces of the EOL puzzle
fall into place in coming weeks!
