Another pgindent gripe

Why does pgindent sometimes insert whitespace into the return type
part of a function definition? Here's an example from the last
pgindent run:

RCS file: /home/projects/pgsql/cvsroot/pgsql/src/backend/optimizer/plan/createplan.c,v
retrieving revision 1.103
retrieving revision 1.104
diff -c -r1.103 -r1.104

--- 1495,1501 ----
return make_sort(sort_tlist, lefttree, numsortkeys);
}
