[developers] prefixation of multi word lexemes

[Stephan Oepen]

hei!

if only to document a (cute, in a sense) debugging case for a known bug
in both the LKB and PET.  woodley and i discovered last night that for,
say, `let's sleep!', we get an extra analysis like this:

  (127 hcomp 0.0 0 3
   (126 punct_sqleft_rule 0.0 0 2 (106 lets_2 0.0 0 2 ("let s " 0 2)))
   (117 punct_bang_rule 0.0 2 3
    (116 bse_verb_infl_rule 0.0 2 3 (109 sleep_v1 0.0 2 3 ("sleep" 2 3)))))

using the following pieces:

  punct_sqleft_rule :=
  %prefix (!f '!f)
  punctuation_sqleft_rule.

  lets_2 := va_lets_imp_le &
  [ STEM < "let", "s" >,
    SYNSEM.PHON.ONSET con ].

all not too surprising, given the current treatment of prefixation, as 
the preprocessor strips off the |'s|.

ann, what is the current status in the discussion of prefixation?  i am
tempted to patch this to always attach prefixes to the left periphery.

                                                         cheers  -  oe
