vc-svn and svn:externals

[ams@gnu.org (Alfred M. Szmidt)]

This makes sure that vc-svn handles the svn:externals property so that
vc-diff/vc-log/... etc work on files that are pulled in via that
mechanism.

2017-09-02  Alfred M. Szmidt  <ams@gnu.org>  (tiny change)

	* lisp/vc/vc-svn.el (vc-svn-parse-status): Don't ignore files
	marked with the svn:externals property.
