commit 0dfcf2dacd4be3f0c647a987b78def5136429165
Merge: 889d358 5eaa1fd
Author: Junio C Hamano <gitster@pobox.com>
Date:   Tue Aug 21 15:27:57 2012 -0700

    Merge branch 'ms/git-svn-1.7' into jch
    
    A series by Michael Schwern via Eric to update git-svn to revamp the
    way URLs are internally passed around, to make it work with SVN 1.7.
    
    Will merge to 'next' after pinging Eric to double check and then to 'master'.
    
    * ms/git-svn-1.7:
      git-svn: remove ad-hoc canonicalizations
      git-svn: canonicalize newly-minted URLs
      git-svn: introduce add_path_to_url function
      git-svn: canonicalize earlier
      git-svn: replace URL escapes with canonicalization
      git-svn: attempt to mimic SVN 1.7 URL canonicalization
      t9107: fix typo
      t9118: workaround inconsistency between SVN versions
      Git::SVN{,::Ra}: canonicalize earlier
      git-svn: path canonicalization uses SVN API
      Git::SVN::Utils: remove irrelevant comment
      git-svn: add join_paths() to safely concatenate paths
      git-svn: factor out _collapse_dotdot function
      git-svn: use SVN 1.7 to canonicalize when possible
      git-svn: move canonicalization to Git::SVN::Utils
      use Git::SVN{,::RA}->url accessor globally
      use Git::SVN->path accessor globally
      Git::SVN::Ra: use accessor for URLs
      Git::SVN: use accessor for URLs internally
      Git::SVN: use accessors internally for path
