Change subject: Update description of LinkCache::forUpdate()
......................................................................
Update description of LinkCache::forUpdate()
The $mForUpdate flag no longer causes the FOR UPDATE option to be added.
This was at first only true for some values of $wgAntiLockFlags (since
r9248 / ba8a00bcb833), though since 12757b50f8da (when the setting was
removed), is always the case.
The added text is based on the description for $wgAntiLockFlags.
