git-rebase.txt: correct antiquated claims about --rebase-merges

When --rebase-merges was first introduced, it only worked with the
`recursive` strategy.  Some time later, it gained support for merges
using the `octopus` strategy.  The limitation of only supporting these
two strategies was documented in 25cff9f109 ("rebase -i --rebase-merges:
add a section to the man page", 2018-04-25) and lifted in e145d99347
("rebase -r: support merge strategies other than `recursive`",
2019-07-31).  However, when the limitation was lifted, the documentation
was not updated.  Update it now.

 If a `merge` command fails for any reason other than merge conflicts (i.e.
 when the merge operation did not even start), it is rescheduled immediately.
 
-At this time, the `merge` command will *always* use the `recursive`

+By default, the `merge` command will use the `recursive` merge
+strategy for regular merges, and `octopus` for octopus merges.  One
+can specify a default strategy for all merges using the `--strategy`
+argument when invoking rebase, or can override specific merges in the

 Note: the first command (`label onto`) labels the revision onto which
 the commits are rebased; The name `onto` is just a convention, as a nod
