New issue 2938 by [email protected]: Pretty print of tall factorials should give tall !'s
http://code.google.com/p/sympy/issues/detail?id=2938

We currently have

In [1]: factorial(x**2/2)
Out[1]:
⎛ 2⎞
⎜x ⎟
⎜──⎟!
⎝2 ⎠

In [2]: factorial2(x**2/2)
Out[2]:
⎛ 2⎞
⎜x ⎟
⎜──⎟!!
⎝2 ⎠

And similarly for ascii. We should print these with tall !'s. In ascii, this is obvious how to do: just make the top part | and the last row ., like

/ 2\|
|x ||
|--||
\2 /.

or maybe

/ 2\ |
|x | |
|--| |
\2 / .

For unicode, I will have to research how to make it look nice.
