bug#37216: [PATCH] vc-svn-ignore sets incorrect properties for relative filenames

[Wolfgang Scherer <Wolfgang.Scherer@gmx.de>]

[-- Attachment #1: Type: text/plain, Size: 182 bytes --]

If a relative filename has at least one level of parent
directories, `vc-svn-ignore' fails to add the ignore spec to the
correct subdirectory.

The attached patch fixes that error.
