Description:
------------
This is a very humble feature request, a little bit of syntactic sugar to make developers happy. Currently, the svn_commit() function requires that the second parameter, $targets, be an array. Many times, developers only want to commit an entire directory, so quite often count($targets) will equal 1. If the targets array accepted a string as a single target, it would be greatly helpful.

Reproduce code:
---------------
svn_commit($log, 'file.txt');

Expected result:
----------------
Same results as if this were called:

svn_commit($log, array('file.txt'));

Actual result:
--------------
Error stating that $targets parameter must be an array.
