Here is additional information:

Ok, in modes where syntax for `"' is "(string quote) - C-M-u gives
error, but why?  Can I simple modify syntax entry for `"' to
.(punctuation) in programming modes without breaking anything?

Consider this picture

  nn("aoeui(aoeu)aoeu")
             ^     ^
             |     |
    (*) point here |
                   |
         (**) point here

For me, in modes where `"' is string quote, C-M-u should jump to open
paren(after double n) in both situations (*) and (**).  But if `"' is
punctuation, then C-M-u should move point to open paren(after i) in
(*) situation, and move point to open paren(after double nn) in (**)
situation.  Am i wrong and missing something?
