| Subject: | backtrack and retry for strings like Some::Module::function |
Some editors all you to pull documentation for the current word, but if the current word is
something like Some::Module::function, cpandoc will not find the correct doc. Since the editor
cannot easily determine which part of the string to look up, and to avoid multiple editors having
to implement similar logic, I propose that cpandoc include the logic. If Some::Module::function is
not found, look up Some::Module, then Some.
