histedit: Don't require argument for fc
This is already handled correctly (per POSIX) below:
When the synopsis form with -s is used:
If first is omitted, the previous command shall be used.
For the synopsis forms without -s:
If first and last are both omitted, the previous 16 commands
shall be listed or the previous single command shall be edited
(based on the -l option).
