fix: compare a citation without the spacing its author chose

A recale rewrites the located tokens and leaves the sentence alone, so a
prose run keeps `a.c:228, 1439-1443` while the rendered form drops the
space. Comparing the two literally made a run that had just been written
look unwritten, pending_recale counted it, and bump_commit refused for
ever.

mariani was held back by three of them: it recaled twenty-five refs and
could never advance its pin, which is the desync the all-or-nothing rule
forbids. 67 refs, all anchored.
