With the current CVS code, I just noticed the following:
(%i1) ? jacobi_sn
-- Function: jacobi_sn (<u>, <m>)
The Jacobian elliptic function sn(u,m).
There are also some inexact matches for `#1=jacobi_sn'.
Try `?? #1#' to see them.
Note the #1 and #1# in the output. Is this something recent? I don't
remember seeing this before. Changing *print-circle* to NIL makes the
output look like it used to.
