Should numpy.sqrt(-1) return 1j rather than nan?

May I suggest the following change to generate_umath.py?
<completely untested string change>
'sqrt' :
Ufunc(1, 1, None,
'square-root elementwise. For real x, the domain is restricted to
x>=0.\n\
For complex results for x<0 see numpy.scimath.sqrt',
TD(inexact, f='sqrt'),
TD(M, f='sqrt'),
),
'
When sqrt throws a ValueError would it be possible/appropriate for the error
message to mention numpy.scimath.sqrt?
I'm just trying to think of other ways to help make the transition as smooth
as possible for new users.
