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,
