Bug 8653 remove erroneous whitespace blocking indexing

Bug 8653 remove erroneous whitespace blocking indexing

The superfluous whitespace after the definition of subject
tag $9s is causing an error when carried over into dom config
files so that the authority links fail to index

Also removed the (harmless) trailing space in the equivalent
Unimarc files

A good editor and git can help in not creating excess whitespace
