Function: remove-list-of-text-properties

Remove some properties from text from START to END.
The third argument LIST-OF-PROPERTIES is a list of property names to remove.
If the optional fourth argument OBJECT is a buffer (or nil, which means
the current buffer), START and END are buffer positions (integers or
markers). If OBJECT is a string, START and END are 0-based indices into it.
Return t if any property was actually removed, nil otherwise.
