Okay, so in the meantime I could make a plugin like netrc_credential_store
which uses the Windows CryptProtectData[1] API functions to add/retrieve
credentials to/from an encrypted store. I can't have auto-caching but at
least it would be encrypted and it should be (relatively) easy to update
it when my password changes with a bzr command provided by the plugin.
