Fails when the opening bracket is in a quoted string

[arkku]

Given code like

printf("%s {",

vim-closer will falsely insert }), instead of the correct )

[arkku]

A possible fix would be to make a configurable set of quotes per filetype and not consider brackets inside those.

Or a simple, cautious, fix would be to have an option to only close brackets when they are the last thing on the line (in which case the ( would also be left open, but IMO that would be the lesser evil).
