Re: [PATCH v2 11/11] vcs-svn,svn-fe: add an option to write svnrev notes

Hi,

There are already a few options to determine svn revision from which
a git commit imported with svn-fe came from. One is to make svn-fe
write a git-svn-id: line to commit messages. Another one is to calc
distance to the root commit. The former includes a "url" and is for
git-svn compatibility, the latter is obviously slow and a bit fragile.

$ svn-fe --notes_ref=notes_tree --ref=branch...
will write annotations for branch commits to the notes_tree, each
annotation is a simple "rN" string. Then these annotations can be
viewed manually or used in incremental import to detect the last
imported revision or to (re)create the import marks for further
imports.

Wouldn't another way be to look at the mark numbers?

I am not sure I like this.  svn-fe is supposed to be a generally
useful tool, and this patch hard-codes the particular note format rN.
If it is needed, maybe it would be possible to do something like

	--notes-ref=refs/notes/svn-rev --note='project foo, r%N'

As a bonus, that would allow including more information using
different flag characters in the note in the future.
