Summary:
xargs supports escaping of newline characters with backslash.
xargs -0 is neither part of POSIX nor the LSB.
This patch removes the -0 option and adjusts the input to xargs
accordingly; that is, the input is a text file not ending in an
incomplete line, and the newline of interest is preceded by a backslash.
Note: The treatment of escaped newline characters is not as clearly
specified by POSIX as for escaped blank characters; however, the same
can be said for escaped backslashes. It is slightly more clear for the
case where the -I option is used; however, -I is also of limited
portability.

This test didn't work as intended and was ultimately disabled some years ago in
r169458.
Indeed it's not clear if the '\n' was ever passed through to the driver
correctly given that lit would insert '&& {' at the newline.
Test rewritten to use printf/xargs to insert '\n' in a more reliable manner and
to use FileCheck for verification.
