Description

I have this vague feeling that this can't be a bug because it would've been noticed already...
But both `o3` and the absence of `o4` seem wrong to me.
```
Macaulay2, version 1.17.2.1
with packages: ConwayPolynomials, Elimination, IntegralClosure, InverseSystems, LLLBases, MinimalPrimes,
PrimaryDecomposition, ReesAlgebra, Saturation, TangentCone

i1 : R = QQ[x,MonomialOrder=>RevLex,Global=>false]

o1 = R

o1 : PolynomialRing

i2 : I=ideal(x-1)

o2 = ideal(- 1 + x)

o2 : Ideal of R

i3 : trim I -- huh?

o3 = ideal 1

o3 : Ideal of R

i4 : R/I -- hangs
^C
Exit (y=yes/n=no/a=abort/b=backtrace)? yes
```
