feature requests - bash history

Hello y'all,

First, I need to say that I'm writing this after some measure of pause, because 
bash is already so richly-featured, and is the product of so much development 
over so much time. However, in my recent use of bash, the following could have 
been useful, and y'all might think would be useful generally.

1] display multiple solutions for a bash history search - Instead of a user 
having to repeat the crtl-r/ctrl-s sequence, and have each solution overwrite 
the previous one, allow the user to prefix ctrl-r/ctrl-s with an integer for 
the maximum number of entries to display. Maybe prefix each solution with it's 
line number in the history, so that the desired solution could be invoked using 

2] Add a feature for history -d to delete more than one line of the history. 
Maybe history -d n,m to delete lines n through m, or history -d n:m to delete m 
lines beginning with line number n.

3] Add a feature for history -d to delete multiple lines based upon a  regular 
history -d n ^man* - delete the n most recent history lines that begin with 
history -d n:m ^man* - delete the first m lines that begin with "man", starting 
at line n.
history -d n,m ^man* - delete all occurrences of ^man* between lines n and m.
