Currently in the docs under "Statistics for join cursors" we get:
|: accesses to the main table
which in addition to being missing "join" before the colon, doesn't document that what actually comes through is "join: table:mytable: accesses to the main table".
This is because the magic that sets up the substitution of the table/index name into the stat name is a little bit too much magic and the code that generates the descriptions into wiredtiger.in can't cope with it.
I tried to fix this naively as part of
WT-9492, but that didn't work (did not understand everything that was going on at the time) and had to revert the change there.
I have a new change that rearranges it all slightly so that the docs come out better.
