I have pushed the proposed change to `widen-limits` branch. The C level
consequences are fairly innocuous. There are only 3 instances of calls to Fwiden

Given that there seem to be use cases of permanent limiting I kept it as buffer
local variable. I also switched to milder name buffer-widen-limits.
