Code review comment for lp:~jelmer/bzr/split-subsegment

Further - and final.

Please test:
",foo=bar" etc
"foo/,foo=bar" etc
"foo/base,foo=bar/other/elements" etc

Please make the shortest functions the ones taking and returning dicts; and the others to be _raw or something; with a note in the docstring that they are lower level functions.
