Well, this fails on versions of bzr.dev < 1877, which report version =
0.9-dev, but do not have bzrlib.ignores (was introduced in 1871), and
then between 1871 and 1877, which does not have 'add_runtime_ignores'.

Which is why I was using direct inspection of what functions/modules are
available, rather than just a version number.

For official releases, it is reasonable to check 'bzrlib.version_info',
but for dev releases we need finer granularity.

(And it doesn't work to just check the revno, because I might be using
an integration or feature branch, which may or may not have merged that
bzr.dev version).

Long term, it only matters that 'bzrtools-0.9' is compatible with
'bzr.dev-0.9'. I can always use my hacked bzrtools until that happens.
