crecord: drop calls to `curses.endwin()`
We got a bug report where `curses.endwin()` failed with `_curses.error: endwin()
returned ERR`. Looking at e306d552dfb12, it seems like we should be able to just
remove these calls.

Regression test for support for the old repos with strange diff encoding. Apparently it used to be possible (maybe it's still possible, but we don't know how) to create commits whose diffs are encoded relative to a nullrev. This test checks that a repo with that encoding can still be read. This is what we did to produce the repo in test-revlog-diff-relative-to-nullrev.tar: - tweak the code in mercurial/revlogutils/deltas.py to produce such "trivial" deltas: > if deltainfo is None: > - deltainfo = self._fullsnapshotinfo(fh, revinfo, target_rev) > + deltainfo = self._builddeltainfo(revinfo, nullrev, fh) - hg init - echo hi > a - hg commit -Am_ - remove some cache files $ tar -xf - < "$TESTDIR"/bundles/test-revlog-diff-relative-to-nullrev.tar $ cd nullrev-diff $ hg debugdeltachain a rev p1 p2 chain# chainlen prev delta 0 -1 -1 1 2 -1 p1 1 0 -1 1 2 -1 p2 2 -1 -1 1 2 -1 p1 $ hg cat --config rhg.cat=true -r 0 a hi $ hg cat --config rhg.cat=true -r 1 a ho $ hg cat --config rhg.cat=true -r 2 a ha $ cd ..
