Is it possible (as in Bash 2.03) to expand an alias
and edit it after ?

You could use this function (e.g. `edit-alias myalias'), if what you want
is to change the definition of the alias.
edit-alias() {
local al
al="$(alias $1)" || return 1
print -z alias $al
}
Otherwise, if you just want the alias inlined in the code, and have a
recent zsh 3.1, try
expand-alias() {
# for safety, in case there's an = which will mess things up...
local alias=${LBUFFER#*=}
if ! alias=$(alias $LBUFFER); then
zle beep
return 1
fi
LBUFFER=${(Q)${alias#*=}}
}
zle -N expand-alias
bindkey '^xa' expand-alias
and hit ^xa just after the alias (I'm assuming it's at the beginning of the
line, else there's more work to be done).
Quite possibly Sven has already added an option to the _expand completer by
now, otherwise I'll try and remember to look at that.
