makefile - Vim: Restart Syntax Highlighting from Arbitrary Line -

i have discovered interesting edge-case in vim syntax highlighting. consider next snippet company makefile:

ldscript := $(subst ",,$(config_sys_ldscript))

the above line removes double quotes given ldscript. nil syntactically wrong; create runs expected , without issue.

the problem

since above line contains 1 double quote, highlighting rules mistakenly think rest of body of makefile quoted text , colors such. simple makefiles, inconvenience; 1kloc+ makefiles, becomes real hassle (especially since preprocessing near top of file).

the question

is there way either disable syntax highlighting based on lines match given regular look (eg. subst[ \t]*['"],.*) or similar? failing that, there way restart vim's highlighting @ arbitrary line while preserving highlights above?

if @ possible, avoid edits makefile script shared across number of departments.

i willing write / modify vimscript accomplish this, have not done before (to reasonable degree). tips, pointers or other helpful hints much appreciated.

what have tried

:syntax sync minlines=1 :syntax sync fromstart :syntax sync clear

none of above seems have effect on highlighting when run in editor. looking through vim help docs, seems :syn-sync-fourth may able after, uncertain how function in inverse manner (eg. disable highlighting rather apply it).

i think best can add together additional syntax rule (in ~/.vim/after/syntax/make.vim) match offending construct. seems work:

syn match makeignore /subst[ \t]*['"],,/ containedin=makeident

the containedin= necessary because it's used in $(...) construct.
