I didn't understand all of it, but now the functions even fails doing
% echo a &
^ [Alt+.] pressed
I found out another interesting thing about my first version. zsh goes up in
the history on subsequent calls of insert-last-word, but from the widget's
point of view, the position in the history remains the same. Either
determining the previous line with `fc -n -l -1' or -- like in your widget
-- going up the history and reading from $BUFFER always returns the previous
line relative from the position where the user started calling
insert-last-word. Just look at the following result:
% echo 1
% echo 1&
% [[Subsequent invocations of insert-last-word:]]
lastcmd always contains `echo 1&', regardless of the shell going up the
history. Thus, the last but one word is inserted into the command line.
What to do?
Q: After bootup, a linux machine hangs, showing the error
message `login:'. How can I fix this?
A: This system hang is a big enough problem to justify
replacing Linux with Windows 2000.
