An unbound symbol can still have symbol properties. Without this, it is painful to eg. look for where a button type or a face is defined.
The way I merged the display of unbound symbols into the rest of helpful-update is... quite inelegant, but avoiding that would require rearchitecting helpful-update to delegate to different "views" instead, so I've opted to not do that for now.
helpful--kind-name
Return "unbound symbol" for symbols that are neither bound as variables or functions.
Also added this case to its unit test.
helpful--summary
Add support for unbound symbols. They are rendered like this: "epg-error is an unbound symbol."
helpful--bound-p
Return non-nil for a lambda instead of erroring out.
helpful-unbound-symbol
New command. Functionally the same as helpful-variable when called from Lisp, but offers only unbound symbols with properties for completion.
helpful-symbol
Call helpful-unbound-symbol for unbound symbols.
helpful--update
Add support for unbound symbols.
helpful--format-references-to-unbound
New function. This returns the text for the references section. Because unbound symbols do not have symbol-file, this unfortunately has to resort to searching every loaded file with elisp-refs.
