I'll debug this on a 10.04 machine. I'll keep the discussion in the
cfengine mailing lists because the mode we're discussing is specifically
hosted by cfengine. I hope that's OK with the moderators.
You can send me bug reports directly if there's confidential information.

Well, the highlighting depends on your settings too. I'm applying
font-lock faces but you could have them empty or undistinguished. I
think the default that comes with Emacs is pretty plain, and only later
versions have color-themes so it's easy to customize all the colors at
once.
Looking at `cfengine3-font-lock-keywords':
- functions get `font-lock-builtin-face'
- variables get `font-lock-variable-name-face'
- variable types, e.g. "slist" get `font-lock-type-face'
...among others. You should have a nice multicolor salad :)

In general I tried to keep the cfengine3 indenting very minimal, you'll
notice that all sections are level 1 and all selectors are level 2
(level 0 being the bundle). All commands are level 3. I think that's
nice because whether or not you have class selectors, the commands
always line up. So, inside a bundle, with indentation of 2 spaces:
section:
# implied any::
dosomething();
selector::
dosomething();
So keep that in mind... some of the indentation makes sense in that
context.
For the attribute 0 indent, it's a feature but I can change it to give
an optional extra indent to continued lines. I was trying to make the
appearance uniform and consistent but I see how it can be useful to
indent attributes.

Oh, I've done that many times :)
