t1502: protect runs of SPs used in the indentation

The expected output from the argument help use runs of SPs to align
the description of each option; a careless use of --whitespace=fix
can turn leading parts of them into appropriate number of HTs.
Prevent such a breakage by prefixing all the expected lines with
leading vertical bars in the original and stripping them with a
small sed script.
