Similar pitfalls can occur in other fields: maybe every heredoc starting with "#!" should be exempted...
The new algorithm doesn't remove all leading whitespace. It removes from each line a *maximum* of whitespace characters as are on the first line of that block. So if I do:
Info2: <<
PatchScript: <<
#!/bin/sh
echo <<END > somefile
foo
bar
iggy
blah
END
<<
<<
Then afterwards somefile contains:
foo
bar
iggy
blah
So it's perfectly possible to continue to include whitespace in a
heredoc if that's needed, in fact that's the whole point of the new
algorithm.
I hope I'm not missing your point, it can be hard to talk about whitespace because you can't see it :-)
