[PATCH] Drop unused options --raw, -n, -e, --include and -I

[Petr Machata]

* --raw appears to be ignored.  It was marked as obsolete in the
  commit ec3bc39, and documented as no longer supported as of 1.29
  (2001-09-07).  Support for %raw appears to have been dropped in
  e9955c83 on 2002-06-11, but --raw was kept around.  Maybe it's time
  to drop it as well?

* Commit e9955c83 dropped support for %no-parser as well, and
  converted it to option.  --no-parser was later dropped in 728c4be2
  on 2007-08-12, but -n was kept around, probably as an omission.  All
  three are documented as removed since 2.3b (2008-05-27).

* -e existed for a single day in 2001.  It was introduced in eeeb962b
  on 2001-11-27.  The handling was removed in c7925b99 on 2001-11-28,
  but "e" was kept in the list of short options.  Probably an
  omission.

* --include appears to be dead code.  The option sets a variable, but
  that variable is not used anywhere.  It was added in f6bd5427 on
  2001-11-26 as a %-directive, with comments that it's not yet
  implemented.  It was converted to a command-line option later, but
  doesn't seem to ever have been actually implemented.
