Details:

hg id 2ae4a7ef4378

create a file foo.m

function myfunction ()
  if (r.
# this comment is important
endfunction


and run 'foo' from Octave gives


ctave:str-to-num: ../../octave/libinterp/parse-tree/lex.ll:2910: int
octave_base_lexer::handle_identifier(): Assertion `!
at_beginning_of_statement' failed.
panic: Aborted -- stopping myself...
attempting to save variables to 'octave-workspace'...
save to 'octave-workspace' complete
Abgebrochen


I stumbled over this because "lookfor" parses all m-files in the current
working directory and stops with the above error because there is unfinished
code in some files.
