It's a bit of both. But the list of states is already provided
inside the documentation of the `info tasks' command, so I added
a couple of references to that section of the manual:
  - One next to the part where I mention the `info tasks' command;
  - One inside the description of the `state' field, mentioning
    explicitly that the list of possible states is described there.

That's a good catch - copy/paste typo. The output is correct, though.

OK. Fixed as suggested.  I also went ahead and modified the others
(that's the second patch, which can be applied independently of
the first).

[Ada/doco] Document the new -ada-task-info GDB/MI command.
gdb/doc/ChangeLog:

        * gdb.texinfo (GDB/MI Ada Tasking Commands): New node.
        (GDB/MI Miscellaneous Commands): Add `ada-task-info'
        as possible feature returned by the `-list-features'
        command.

[doco] rephrase `presence of' with `support for'.
gdb/doc/ChangeLog:

        * gdb.texinfo (GDB/MI Miscellaneous Commands): Minor
        rephasing.
