The patch to lex.l that you sent me to solve the

  a = [-1-i -1+i]

problem resulted in odd behavior:

octave1> schur
octave1> schur
usage: [U,S] = schur (A)
           S = schur (A)
 or for ordered Schur:
       [U,S] = schur (A,'C, D, or U')
           S = schur (A,'C, D, or U')
 where C stands for continuous time poles
 and D for discrete time poles
 and U for unordered schur (default)

octave2> a = [0 1; 0 0]
octave2> a
a =

  0  1
  0  0


Every other command was incompletely processed.
I restored lex.l and lex.cc from octave-0.72.tar.Z and things
work as expected (other than the original bug).
