POSIX states:
When a range of commands is used, it shall not be an error to specify
first or last values that are not in the history list; fc shall
substitute the value representing the oldest or newest command in the
list, as appropriate. For example, if there are only ten commands in
the history list, numbered 1 to 10:
fc -l
fc 1 99
shall list and edit, respectively, all ten commands.
Which would seem to imply that the current fc shouldn't be included
(well, in the POSIX model, no non--l fc enters the history,
so that reinforces that).
zsh, bash, mksh, yash all agree with this; oddly, ksh includes it.
