Include #+INCLUDE'd files in wordcount

[spacekitteh]

So I have several files with different parts of my document in them, and org-wc doesn't include their word count in its count. Is there a way to do this?

Not as it stands. There's no knowledge of included files in org-wc. Pull request welcome, if you're up for it.

This is also somewhat tricky, as the INCLUDE keyword can select what parts of the file to include in complex ways. It won’t work to just jump into the file, count words there, and include it.
Doing this "right" would involve doing the same steps as org-export, where the buffer is copied to a temporary buffer and INCLUDE keywords "expanded" (correct parts included and trees shifted). See org-export-as and org-export-expand-include-keyword. So we would need to make a buffer copy and run org-wc there, which presents some new problems (more complicated to put word count overlays on subtrees for example).
