Changed behaviour of series() involving exp, I #24266
Description
Commit 7293447 changes the behaviour of series for the exp function, is the new output preferred for some reason?
Before commit
from sympy import *
x = symbols('x')
print((exp(-I*pi*(2*x+1))).series(x,0,3))
print((exp(-I*pi*(2*x+1))*gamma(1+x)).series(x,0,3))
gives
-1 + 2*I*pi*x + 2*pi**2*x**2 + O(x**3)
-1 + x*(EulerGamma + 2*I*pi) + x**2*(-EulerGamma**2/2 + 23*pi**2/12 - 2*EulerGamma*I*pi) + O(x**3)
After commit
exp(-I*pi*(2*x + 1))
-1 + EulerGamma*x + x**2*(-pi**2/12 - EulerGamma**2/2) + O(x**3)
Now the exponential is not expanded, unless multiplied by some other function (for some reason?), and the branch cut/analytic continuation has been changed.
Thanks for any input on the desired behaviour.
