15830 extracting coefficient x-1 out of symbolic series wrong dkrenn "{{{
sage: x.series(x==1,10).coefficient(x-1,0)

which is wrong. It should be {{{1}}}, which can be seen by
{{{
sage: x.series(x==1,10)
1 + 1*(x - 1)
}}}
We also have wrong results here:
{{{

sage: x.series(x==1,10).coefficient(x-1)
0
