feature request: capture output of last command and make it available on some hotkey

[Jörn Hees]

Hi,

i think this would be a very useful feature and i don't seem to be alone:

http://unix.stackexchange.com/questions/9024/how-do-i-reuse-the-last-output-from-the-command-line

There are a lot of hackish solutions how you could achieve this, but since 
readline actually provides the yank-last-arg it would somehow be cool to also 
have a yank-last-output-line, maybe on M-, instead of M-.

As outputs might get pretty big, maybe bash could remember up to the the first 
and last 10 lines of output of the previous command. After that counting 
usually gets slower than using another approach anyhow.

Use cases:
- type some command, realize you want to do something with the last line of the 
output, for example view the path written there, type "less ", hit [esc] [,], 
done…
- whenever you used your mouse to copy that one line from the last output just 
to reinsert it after the command you just typed.

Cheers,
Jörn
