~indent:true generates broken HTML

[zapashcanon]

Hi,

This is quite similar to #287 and #288 but more annoying...

When using br () and ~indent:true, sometimes there will be a line break in the middle of the generated <br />, for instance:

... <
... br />

Thus the produced HTML is invalid (< is not escaped...) and <br/> will even be displayed in the rendered page, which is of course problematic.

grmbl, this is getting quite annoying indeed. I think we should just find better ways to externalize this printing to lambdasoup and make that the easy path.
