Empty line is ignored when copy text

[jcubic]

Expected behavior

There should be blank space in copy text

Actual behavior

Text is merged.

Steps to reproduce

1. Open my lisp demo and type:
2. type:

(help ..)
(help string->symbol)

you will get this:

copy the text, you will get this:

lips> (help ..)
(.. foo.bar.baz)
Macro that gets value from nested object where argument is comma separated symbol
lips> (help string->symbol)
(string->symbol string)
   Function convert string to LIPS symbol.
lips> 

the problem may be in css of the selection:

but maybe it will require to fix the code that process the selection text when copy.
