keeping tests/*/raw_out_parser

[Patrice Dumas]

Hello,

To debug the use of tex4ht and latex2html, it is much better to keep 
tests/*/raw_out_parser.  For most other cases it is not as important as 
there is no difference between out_parser and raw_out_parser.  

Would it be ok to keep the directory?  It may require removing all the
raw_out_parser files for make distcheck, though.
