Subject: readline tab completion -- the whole line?

Recently, a thread about tab completion showed me
   Readline.completion_proc = Proc new {|prefix| ... }

and while that is an improvement for my little apps, I wonder whether the
block can get more than the current word on the line, i.e.
  little> save lo[TAB]
gives me the prefix (passed as param to the block) "lo", not e.g. "save lo"
or ["save", "lo"] so basically I can not use the context in a nice way (use
"localfile" in this case, not "load").

I figured I can do
  Readline.basic_word_break_characters = ""
after which I get the entire line (which I can then #split by hand).

Am I missing something? Is readline (despite its weight) so primitive?

Bye,
Kero.
