Thank you for your answer. Sorry I missed your earlier post I just read it now.
It is clear indeed that it is not a thing that can be implemented very quickly.
I took a quick look at the readline library. I think it should be possible to
change readline's commands "history-search-forward" and
"history-search-backward", so that they match "real substrings" instead of
"left substrings". [I don't feel very comfortable with "reverse-search-history"
and "forward-search-history".]
The other part, "on the fly highlighting and underlining" will be a lot more
difficult to implement.

I am not fluent at c, I guess the language in which Bash is written. So I am
afraid that would be beyond my capabilities.

Very good idea! Many more regular Bash users will probably be interested in
these Fish features. I will write up a draft this for an email that we may send
to the Bash devs. I will first drop it here to collect comments from you and
other Fish users.
Best wishes,
