Summary: Ref T12970. See PHI43. Currently, the "Show Older Comments" link gets auto-clicked if the user visits **any** anchor. This is not correct. Instead, only auto-click it if the user visits a numeric anchor. This fixes the behavior approximately 98% of the time. See T12970 for a followup on the remaining ambiguous cases. Test Plan: - Viewed a revision with some folded transactions and a "Show Older Comments" link. - Clicked a link to a file in the table of contents, with a hash like `#1234abcd`. - Before: Timeline expanded and I ended up somewhere bad. - After: Timeline no longer expanded. - Manually changed hash to `#1234` (purely numeric), saw timeline expand.
