Merge branch 'rj/path-cleanup'

* rj/path-cleanup:
  Call mkpathdup() rather than xstrdup(mkpath(...))
  Call git_pathdup() rather than xstrdup(git_path("..."))
  path.c: Use vsnpath() in the implementation of git_path()
  path.c: Don't discard the return value of vsnpath()
  path.c: Remove the 'git_' prefix from a file scope function
