Can the argument have embedded (escaped) quotes, as in "foo\"bar", in
some language?  If it can, the search for the next quote is certainly
not the right thing to do.

One situation where this could happen is when a breakpoint uses the 
file:line notation, since file names could have embedded quotes.
