repoview: fix typo in repoview.changelog Incidentally, this avoids the changelog cache being invalidated each time it's accessed on a repoview. On a filtering experiment on a repository the size of mozilla-central, this makes a significant difference: Before, running hg log -l 10 --time with about 8k changesets filtered out: time: real 1.490 secs (user 1.450+0.000 sys 0.040+0.000) After: time: real 0.540 secs (user 0.530+0.000 sys 0.010+0.000)
