It is a good idea to use something like "sed -e 's/^|//'" instead of
"cat" here; that way allows you to mark the left-edge of the data
with "|", for a test vector like this one that has a line that would
otherwise violate the whitespace style rules.  

An inferiour alternative would be to add .gitaddtibute entry to make
this file exempt from indent-with-tab rule, but even in this 40-line
block there only is one line that requires such a workaround, and it
won't help the initial application of this patch to get modified
when applied with "am --whitespace=fix".
