[bug #61079] [groff] check of reg...59202.sh returns one

[Bjarni Ingi Gislason]

Follow-up Comment #4, bug #61079 (project groff):

  My "make check" returned FAIL again.

  I checked it three times with and without -j and all caused
FAIL.

  As it looked like a race condition I checked three times with
"sleep 5" between the commands and equally often with "sleep 1" with a
PASS result in all cases.

  The sequence of the commands is necessary for a right result,
so the shell must be told to do so.

  The script uses:

echo | "$groff" >&-
! test -e core

  As the first line returns false,
adding " || \" to that line should insure that it will be executed first
and finished before next line is executed.

  If the command in the first line would return true,
then the next line is superfluous.
