creates not a cursor.  Patch by Xiang Zhang.

In Subversion r86731, the path was changed from $(BINLIBDEST)/config to
$(LIBDEST)/config-$(LDVERSION).

Also adjust the test condition, because enable-meta-key was only added in
6.1, not 6.0.

Statements should not be reset after a commit.

* Memove -t option of ctags. The option was kept for backward compatibility,
  but it was completly removed recently. Patch written by Stéphane Wirtel.
* Set locale to C to call sort. vim expects that the tags file is sorted using
  english collation, so it fails if the locale is french for example. Use
  LC_ALL=C to force english sorting order. .

If Popen.communicate() raises an exception, kill the child process to not leave
a running child process in background and maybe create a zombi process.

This change fixes a ResourceWarning in Python 3.6 when unit tests are
