[Van L]

Hello,

I am looking for a one-space after punctuation sentence-ending for M-e to jump 
by.

Disabling the following variable stops short at Nov. or Gov. (see below) 

┌────
│ (setq sentence-end-double-space nil)
└────

┌────
│ Haley’s departure also stoked speculation she could replace Lindsey Graham as 
the senator from
│ South Carolina, a possibility that Trump played down. Talk in Washington is 
that should Trump
│ replace Attorney General Jeff Sessions with Graham after the Nov. 6 
congressional elections,
│ South Carolina Gov. Henry McMaster would be responsible for selecting a 
replacement to serve
│ until the 2020 election. McMaster was previously Haley’s No. 2 in the state.
└────

and I’m aware of names like A. B. C. Nurmagomedov which will stop early, too.

What rules specify an almost perfect spot for the end of a sentence followed by 
single space?; to fit in the sentence-end function. 

Is WordNet useful for this?
