checking a package changes the namespace

[mikestillman]

The following code appears to assign a value to f.

needsPackage "Complexes"
check Complexes
f

Ah, it's because I'm passing the UserMode option of check to capture:

M2/M2/Macaulay2/m2/testing.m2

Line 43 in 9a7832b

(err, output) := capture(teststring, PackageExports => pkg, UserMode => usermode);

If you do check(Complexes, UserMode => false) it should go away, or if you start M2 with -q.

But perhaps we should change this. Either default value of [check, UserMode] should be false, or check should always pass UserMode => false to capture. Which would you prefer?
