Old description:
> This should work instead of needing '''{;}''' :

> {{{
> :{
> let f = do
> one
> two
> three
> :}
> }}}
>
> Also the up arrow key should bring back the whole block (and allow
> navigating within it), skipping to the next or previous block or command
> when going past the ''':}''' or ''':{'''.
New description:
GHCi accepts multiline input in the form of:
{{{
Prelude> :{
Prelude| let f = do
Prelude| print "Hello"
Prelude| print "World"
Prelude| :}
}}}
OR of the form:
{{{
Prelude> :set +m
Prelude| let f = do
Prelude| print "Hello"
Prelude| print "World"
Prelude|
Prelude>
}}}
However, recalling mulitline input from history (with the <Up> key or
<C-p>) recalls it as its individual lines, not the whole input. Ideally
multiline should be one history entry and allow proper editing of the
recalled text.
