Shell prompts can be fairly long, so it would be nice to split the prompt over two lines, e.g.

[oracle]:[niels]:/home/oracle
$

To reproduce this prompt in fluidshell use:

declare -x PROMPT="[\\\${USERNAME}]:[\\\${DATABASE}]:\\\${PWD}\$ "

That worked fine - but I wanted a multiline prompt which can be achieved using:

declare -x PROMPT="[\\\${USERNAME}]:[\\\${DATABASE}]:\\\${PWD}
\$ "

However - While the prompt displays properly, e.g.

[ajpowell]:[WG0036]:[master]:Q:\SQL\SQLServer
$

any subsequent command does not display correctly, each keypress seems to introduce a line feed.
