     The proj thread contexts have not seen widespread use, so one of the
     intentions with this new API is to make them less visible on the API
     surface.
-    
+
     A series of experiments have, however, shown that they, for (mostly)
     historical reasons, are very hard to eliminate totally. But we have
     reduced their API surface presence to a constructor and a destructor,
     plus an extra argument to the PJ constructor, pj_create().
-    
+
     For single threaded programs, the calls to the context constructor
     and destructor may be left out, and the default context selected
     by passing a null-pointer to pj_create.
