This reimplements ridiculousfish/control_r which is a more future-proof approach than #6686. Pressing Control+R shows history in our pager and allows to search filter commands with the pager search field. On the surface, this works just like in other shells; though there are some differences. - Our pager shows multiple results at a time. - Other shells allow to use up arrow/down arrow to select adjacent entries in history. Shouldn't be hard to implement but the hidden state might confuse users and it doesn't play well with up-or-search, so this is left out. Users might expect the history pager to use subsequence matching (fuzzy matching) like the completion pager, however due to the history pager design it uses substring matching. We could change this in future, however that means we would also want to change the ordering from "reverse-chronological" to "longest common subsequence" (e.g. what fuzzy finders do), because otherwise a query "fis" might give this ordering: fsck /dev/disk/by-partlabel/Linux\x20filesystem fish which is probably not what the user wants. The pager shows only a small number of history items at a time. This is because, as explained above, the history pager does not support subsequence matching, so navigating it does not scale well. Closes #602
