There is an inconsistency with the documentation and behavior of the ^ word
designator. According to documentation, it refers to the first argument but
does not require a ':' before it if it starts the word designator. However,
it does not act like the numerical word designator 1 at the end of a range.
Thanks for the report. This is a bug.
[root@localhost ~]# echo a b c
a b c
[root@localhost ~]# echo !!:1-1
echo a
a
[root@localhost ~]# echo a b c
a b c
[root@localhost ~]# echo !!:^-^
echo a b^
a b^
Also it is not explicitly documented that :- is equivalent to :0-
Thanks, I'll add a note to the documentation.
