This works in Firefox but not in Safari: use whitespace, and then have
this style somewhere:

option {white-space: pre}

Alternatively I like Yar HweeBoon's suggestion of having a special
IndentedString class with its own #renderOn: implementation, although
I might just have a PreformattedWhitespace class instead - and for
convenience, add a #preformatted method to String which returns one. 
So you end up with something like this:

html selectFromList: items selected: foo callback: bar labels:
   [:ea |
   (self indentedStringFor: ea) preformatted]
