Damn. I've just pulled 'patterns' out as a separate help topic that
both rules and ignore refer to based on the fact that the pattern language
is shared. I wonder also whether regular expressions might be useful for
ids, particularly in the BZR_HOME/rules file. It would allow us to
set preferences just for files managed by bzr-svn say ...

  [id RE:^svn:]

It sounds like 'for' feels too much like a looping construct so I'll
switch to 'name'.
