Further info on Example 1: in the fail scenario, it seems that while the check
does indeed fail, and the package is (re)installed, the post-install check
succeeds!

>From the log output:

2009-01-13 14:42:22, DEBUG  : Checking existence of package: Firefox extension
flashblock
2009-01-13 14:42:22, DEBUG  : The path 'C:\Program Files\Mozilla
Firefox\extensions\%ffextid%\install.rdf' does not exist: the test failed
.
. install happens here ...
.
2009-01-13 14:42:30, DEBUG  : Checking existence of package: Firefox extension
flashblock
2009-01-13 14:42:30, DEBUG  : The path 'C:\Program Files\Mozilla
Firefox\extensions\{3d7eb24f-2740-49df-8937-200b1cc08f8a}\install.rdf' exists:
the test was successful


So %ffextid% was correctly expanded/interpolated on the second run of the
check, but not the first time!

Ahh, looking more closely at the log, it appears that the variables defined in
the package aren't actually evaluated before the checks are run, only when an
install is run. Is this a bug?
I think that explains the observed behaviour for Example 1, though not Example
2.
