space-before-citation (REF011)

What it does

Checks that a hard space (~) precedes each \cite command. This rule is disabled by default. Enable it with --select REF011 or add REF011 to lint.select in the TeXact configuration.

Why is this bad?

A hard space keeps the citation attached to the preceding word and prevents a line break before the citation.
