Subject: Git::SVN: use accessors internally for path
X-Git-Tag: v1.8.0-rc0~155^2~19
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=5578ed744ddcf4e43d4fffa40fe3c76e38a91d11;p=git.git

Git::SVN: use accessors internally for path

Then later it can be canonicalized automatically rather than everywhere
its used.

Later patch will make other things use it.

[ew: commit title, reformatted accessor to match existing style]
