Here is my point: I believe (re-search-forward "\\s_" nil t) should find
"+" character in lisp/scheme modes because it may be part of symbol
names there.  Even elisp manual mentions this fact:

https://www.gnu.org/software/emacs/manual/html_node/elisp/Syntax-Class-Table.html#Syntax-Class-Table

So I think that ".dir-locals.el" shouldn't break this default behavior.
