tocloft: part formatting doesn't happen because \numberline is omitted

[wspr]

A typical .toc file looks like this:

\contentsline {part}{I\hspace {1em}I want to enlarge the space between the label and the content}{2}
\contentsline {chapter}{\numberline {1}Introduction}{3}
\contentsline {section}{\numberline {1.1}Just a sample section}{3}
\contentsline {subsection}{\numberline {1.1.1}Explain}{3}

Note that part doesn't use \numberline. Therefore, we need to be a bit smarter with how we try and format that ToC entry. Should be able to check if the token list contains \numberline, if not branch and check if it contains \hspace, then parse out the hard-coded formatting and insert the required internal tocloft macros.

Or just patch the \part macro… it's an unfortunate situation!
