The fix for bug 48418 made the assumption that {CREDITS|AUTHORS}.* files were wikitext (with the implication that wikitext bullets should precede each file), contrary to expectations.
Instead, we should treat their contents as the plain text they (mostly) were until this feature was added, and merely wrap them in <pre>s for Special:Version/Credits/… etc. purposes.
Version: unspecified
Severity: minor
