Ooops. Right it was: in chapter 2 as some "operator not printed by \c", and
right next to the conj() function in chapter 3 (I knew I should have read
this manual before rewriting it).

  Presumably due to my poor standard of English / sense of humour / both, I'm
experiencing trouble making sense out of this. Basically, you're happy to
have a key that, when pressed inadvertently, sometimes happen not to have any
adverse effect whatsoever, right? (got a solution for you then: insert the


in your .inputrc (enclosed within $if Pari-GP / $endif if you still
want it in bash...))

The clock gets updated whenever the prompt is, which means just before it
is printed again (hence, case a).
