In `grep_splice_or()` we search for the next `TRUE` node in our tree of
grep exrpessions and replace it with the given new expression. But we
don't free the old node, which causes a memory leak. Plug it.
This leak is exposed by t7810, but plugging it alone isn't sufficient to
make the test suite pass.
