[gentoo-portage-dev] [PATCH v2] svn sync: fix the module

[Michał Górny]

Fix the svn sync module since it doesn't work at all right now. More
specifically:

1. add exists() method that checks for the '.svn' directory to determine
whether the repository was checked out already.

2. Fix the initial clone to use valid svn commands. Do not remove
the just-created (in pre_sync()) directory to avoid permission issues,
just run checkout on top of it.

3. Fix the sync method to run update unconditionally to whether the URI
starts with svn:// or not. In fact, remove the whole check since it
doesn't serve any purpose.
