[PATCH] Remove redundant member skip_descendants from libsvn_wc/update_editor.c

Hi All,

In my pursuit to understand libsvn_wc/update_editor.c I came across an
unnecessary member (skip_descendants) in the dir_baton. skip_descendants
and skip_this are being set at the same time and have identical values
at all times. I have removed one of these (skip_descendants) and the
*relevant* code that I understand as being unreachable. I have attached
the patch and a log message. Please review and respond.

Regards,
Arwin Arni
