devel/svn2git: Backport svn 1.9 fix

- Backport an  pull-request to fix an issue with SVN 1.9 [1]. This is
  running in the FreeBSD cluster (by peter@) to fix a regression after
  upgrading SVN.
  
While I'm here:

- Use OPTIONS helpers for FREEBSD_REPO
- Make patches makepatch compatible (portlint)
- Whitespace align OPTIONS_*

PR:		204023
MFH:		2015Q4

Test Plan

• portlint: OK (looks fine.)
• testport: OK (poudriere, 93amd64)

The new patch shows up as an empty file? Otherwise LGTM

Yeh sorry, thats an arc(8) bug cc again again @eadler

Give me a sec and i'll update the diff manually (again again again)

[koobs]

Manually update diff to include new added file contents because phabricator/arc is broken

[uqs]

Can we get this submitted already?

I was under the impression @peter had already patched it in the cluster.

Alas, this patch is not enough. svn 1.9 plus a patched svn2git still dies on rev 20 of the base svn repo :(

Has a solution been found? Should I commit this patch regardless?
