I tried to use “make patchcheck” after edits to reST files and it hung.  Do you have the same behavior?  I suspect reindent-rst is the culprit.

I’m wondering about the reindenting; other checks in patchcheck don’t edit files, they just print warnings.  On the other hand, removing trailing whitespace and reindenting is not a very good use of people’s time, so having a tool do them is good.
