view runtime/syntax/prolog.vim @ 3254:2f075595590f v7.3.396

updated for version 7.3.396 Problem: After forcing an operator to be characterwise it can still become linewise when spanning whole lines. Solution: Don't make the operator linewise when motion_force was set. (Christian Brabandt)

" There are two sets of highlighting in here:
" If the "prolog_highlighting_clean" variable exists, it is rather sparse.
" Otherwise you get more highlighting.

" Prolog is case sensitive.

" Very simple highlighting for comments, clause heads and
