Comment(by warren):

 Let's try that again, with one more item in the summary list...

 ''Changes to toeplitz()''

 1. Always returns a 2D array, even if either argument is a scalar.

 2. When c is complex and r is not given, r=c.conj() is assumed. The first
 column is always c, not c.conj().

 3. The first element of r is always ignored; the function never prints a
 warning if c[0] != r[0]. The docstring explains that r[0] is always
 ignored.

 4. asarray_chkfinite() is no longer used.  There is no reason for the
 function to disallow nan or inf values in the array.
