Comment 2 for bug 716135

It appears "svn-keywords = Rev" has 3 interpretations:
 * Rev values expanded like Svn client: ongoing interaction with an Svn repo
 * Rev values replaced with Bzr revision numbers: migrated repo (which will never again talk to the Svn repo) without Bzr Keywords installed
 * Rev values replaced with Bzr revision identifiers: new or migrated repo with Bzr Keywords installed

How would I go about expanding "Rev" keywords like an Svn client (touching the values only when pulling/importing from Svn) and "Revision-Id" like a Bzr client? At present it appears I have to temporarily toggle "svn-keywords" and "keywords" rules.
