it's negative.

Fix will appear in 0.76.

I've added a change along the lines of the one documented
here.
Its not at all clear to me that the one provided will work.
Specifically,
the process_limit() function includes this code:

if (limit_item == LIMIT_PRI) {
/* additional check */
pl->priority = ((limit_value>0)?limit_value:0);
} else {

which appeared to enforce the notion that the limit be non
-ve. I've
removed this code as part of this bug report.
