[PATCH 2/4] t9810: Do not use sed -i

[Torsten Bögershausen]

sed -i is not portable on all systems.
Use sed with different input and output files.
Utilize a tmp file whenever needed

Making it shorter and more correct ;-), which is good, but you are
losing the && chaining.  Also it is more customary to have
redirection at the end, unless it is to redirect a numbered file
descriptor (e.g. "echo >&2 error message").  I.e.

	sed "s/Revision/Revision: do not scrub me/" <filek >fileko &&
	sed "s/Id/Id: do not scrub me/" <fileko >file_text
