Removing the contributors file. While the project is immensely grateful for each and every contribution, a flat file of contributors is an extra burden for maintenance and has the potential to leave some contributors unacknowledged. Given the detailed use of the source code tools and references to the issue tracking systems, the actual contributions of each and every contributor, large or small, are transparently described. Thanks go out to all.

This is the best that can probably be done.  Temporary directories are used
for get the svn binary version and to get the initial directory info (for
determining if one is, in fact, in a svn working directory)

ALSO: The check for SVN was not right.  Decided on files to only check for
.svn/entries because missing properties just leaves out the external refs.
And then incorporated a test on the code to make sure that svn info completed.

Test passed on CPytonh 2.x and 2.3 on windows, travis-ci, and travis-ci/mac.
Note: There seems to be an issue with pypy and a test.
