doc parsing error with (''a -> {Exception}'')

[ceedubs]

Here's a strange one. When using double single quotes ('') to create fixed-width text, the following examples work fine:

• ''{Exception}''
• (''{Exception}'')
• ''() -> {Exception}''
• ''a -> {Exception}''

But the following create errors:

• (''() -> {Exception}'') (I couldn't find any definitions matching the name Exception inside the namespace)
• (''a -> {Exception}'') (I couldn't find any definitions matching the name Exception inside the namespace)

Note the parentheses outside the quotes that seem to be tripping up the parser.
