To be truly useful, the sequencer should never die() but always return
an error.

I am still looking at sequencer.c in 'master', but I do not think
that the sole caller of this function, walk_revs_populate_todo(),
is prepared to act on an error return from this function and instead
it expects this to die() when in trouble.  And I do not think I saw
the function touched in the steps so far.

So this step smells like a fishy conversion to me.

The fishy part is, of course, that I managed not to realize that the patch
libifiying walk_revs_populate_todo() came *after* this patch that libified
one of its callees, prepare_revs().

FWIW the same is true for sequencer_pick_revisions(), which was libified
way too late in the game.

This is once again a demonstration that a final patch series does *not*
reflect the process of developing it: in this case, the order of the
patches is the *opposite* of their development, as I libified functions
from the lowest, deepest call depth up to the top-level functions.

Fixed in v2,
