Thanks it works, but complains that its not properly convergent.
I changed the replace pattern to include a negative lookahead
"^(?!$($(v)[$(pattern)]))$(pattern)"
And it stopped complaining. So it does work, but boy
"limits[^\s*sybase\s*hard\s*memlock\s.*$]" string => "sybase hard
memlock 10000";
That seems like a poor way to communicate meaning.
Here is the edited version as well.
