No, indeed.  There's probably another setting available that can fix
that case, tho.

It's possible that your patch is actually safe.

Someone™ just needs to take a close look at the syntax-propertize,
font-lock, and indentation code to assess the potential effects (I think
it's the only two cases that deserve such close scrutiny, because other
cases are usually more like dabbrev in the sense that there isn't as
clear a "right-vs-wrong" distinction).

Another option, might be to combine your patch with another patch which
sets the syntax-table used for font-lock, indentation, and syntax-ppss.
