Document that when using git svn, one should usually either use the directory structure options to import branches as branches, or only import one subdirectory. The default behaviour of cloning all branches and tags as subdirectories in the working copy is usually not what the user wants.

It is considered bad practice to --amend commits you've already pushed to a remote repository for other users, and dcommit with SVN is analogous to that. +When cloning an SVN repository, if none of the options for describing +the repository layout is used (--trunk, --tags, --branches, +--stdlayout), 'git svn clone' will create a git repository with +completely linear history, where branches and tags appear as separate +folders in the working copy.
