bug#7219: Parentheses matching cursor blink in wrong place

[Eric Mullen]

Also, to give you some more test cases, the following lines also are
subject to this bug:

\textbf{First($<exp>$) = $\{ ``('', ``a'' \}$ }
\textbf{First($<tuple>$) = $\{ ``('', ``a'' \}$ }

However, this line is not subject to it (for some reason)

\textbf{First($<expTail>$) = $\{``e'', ``,'' \}$ }
