[developers] `-yy' option to (the `main' version of) cheap

[Stephan Oepen]

howdy,

francis and i just observed that the `main' branch of cheap has changed
the `-yy' option in a way that appears to not be backwards-compatible?
after a bit of poking, it emerged that francis had to say `-tok=yy' to
get a cheap that works with the original JaCY ChaSen interface.

i would not be sad at all if more of the YY-specific code (specifically
the K2Y and now defunct native MRS support) would disappear, but i fear
the `-yy' option (turning on YY input mode) is something people have in
active use.  hence, i would suggest to keep its semantics in the `main'
branch too.  the following patch, i expect, should be sufficient:

  *** /tmp/options.cpp    2005-07-04 18:48:38.000000000 +0200
  --- /tmp/options.cpp-   2005-07-04 18:48:27.000000000 +0200
  ***************
  *** 470,479 ****
              opt_k2y_segregation = true;
              break;
          case OPTION_YY:
  -           opt_tok = TOKENIZER_YY
              opt_yy = true;
              break;
  - 
    #endif
            }
        }
  --- 470,477 ----

bernd, would you mind integrating this?  the behavior francis and i got
from the current code was misleading, as `-yy' is still accepted as an
option, only it no longer has the effect it used to have ...

                                         many thanks in advance  -  oe
