erroneous hdfdump output of multiline (heredoc) elements

[Narcelio Filho <narcelio+filho@…>]

Multi-line HDF elements are being generated wrong for hdfdump. HDFWrapper generates this:

foo {
 bar = << EOM
line1
line2
EOM
}

when should generate this:

foo {
 bar << EOM
line1
line2
EOM
}

(without the equal sign)

Clearsilver tool chokes when feed with first example:

$ cs -h test.hdf
Traceback (innermost last):
  File "neo_hdf.c", line 1840, in hdf_read_file()
  File "neo_hdf.c", line 1678, in _hdf_read_string()
    In file test.hdf:3
  File "neo_hdf.c", line 1739, in _hdf_read_string()
ParseError: [test.hdf:3] Unable to parse line line1

We're dropping support for ClearSilver, so there's no real need for that anymore. However, if someone else feels like committing the patch, please do.
