commit after pull from 3.2

Hg-commit: 12bf7f190e2a9b0eafa5d8c78eb160b07da3d705

Fix problem in TSGL where TSGLAdaptSetFromOptions() was not reached.

PetscOptionsTail() contains a return statement, so code cannot reliably
be placed after it (in light of the deeper issue below).

Fix problem in TSGL where TSGLAdaptSetFromOptions() was not reached.

PetscOptionsTail() contains a return statement, so code cannot reliably
be placed after it (in light of the deeper issue below).

I need to remove TSGLAdapt and make TSGL use TSAdapt, which the other
methods are already using.

Deeper issue: PetscOptionsBegin() unconditionally increments
PetscOptionsPublishCount. This should be changed so that
PetscOptionsBegin() is like PetscOptionsHead() when called within an
active options loop. That is too big of a change for petsc-3.2, so it
does not accompany this patch.
