git-svn: Recommend use of structure options.

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.

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
directories in the working copy. While this is the easiest way to get a
copy of a complete repository, for projects with many branches it will
lead to a working copy many times larger than just the trunk. Thus for
projects using the standard directory structure (trunk/branches/tags),
it is recommended to clone with option '--stdlayout'. If the project
uses a non-standard structure, and/or if branches and tags are not
required, it is easiest to only clone one directory (typically trunk),
without giving any repository layout options. If the full history with
branches and tags is required, the options '--trunk' / '--branches' /
'--tags' must be used.
When using multiple --branches or --tags, 'git svn' does not automatically
handle name collisions (for example, if two branches from different paths have
the same name, or if a branch and a tag have the same name). In these cases,
