git-svn: allow metadata options to be specified with 'init' and 'clone'

Since the options that affect the way metadata is handled in
git-svn, should be consistently set/unset throughout history
imported by git-svn; it makes sense to allow the user to set
certain options from the command-line that will write to the
config file when initially creating the repository.

Also, fix some formatting issues while we're updating
documentation.

 options all affect the metadata generated and used by git-svn; they
 *must* be set in the configuration file before any history is imported
