Add -c and -d options to history

[jyn514]

Sometimes I type in my password to the shell instead of sudo by mistake. It would be nice to have an option to delete it with history -c instead of having to find the history for osh and delete it manually. From help history in bash:

history: history [-c] [-d offset] [n] or history -anrw [filename] or history -ps arg [arg...]
    Display or manipulate the history list.
    
    Display the history list with line numbers, prefixing each modified
    entry with a `*'.  An argument of N lists only the last N entries.
    
    Options:
      -c        clear the history list by deleting all of the entries
      -d offset delete the history entry at position OFFSET.

Yes, I recall seeing this in some programs, maybe it was fzf #322

FWIW #562 and #358 are user requests for history flags/features. I guess people use this builtin a lot more than I do!
