better history suggestions

[maxomatic458]

I think it would be cool if the history suggestions wouldn't just work for full commands but also for sub-commands/strings.

e.g i run the command clear

in the shell i will get the history suggestion for it, but only if i didnt enter anything else yet.

echo "test"; c will not suggest clear here

this would be especially useful in cases like this:

scp path/to/some/file/ [email protected]:~

if someone would want to upload another file, they wouln't get a suggestion for the second part, so [email protected]:~ would need to fully by typed out again;
