count: Prevent line breaks in the middle of 'and n.m'

This commit touches paragraphs where a sequence of multiple
cross references can be handled by a \cref{} command as follows:

    \cref{label:a,label:b}

Also fix a typo in plural tense.

Substitute ";" for "," in a label string, which is incompatible
with cleveref, as well.
