3.0a5, Windows, Python Manuals window opened from Start menu
Ordinary text wraps and adjusts to window width.
Text in green boxes does not. If too long to fit window, given the font
size, horizontal scroll bar at bottom gives access to overflow.
Example: LibMan.StringServices.CommonOps.FormatSyntax.FormatSpecMiniLang
type ::= "b" | .... | "%"

However, when I move the bar right, moving the text left, the newly
visible part of the window coming in from the right is dark blue green
instead of white and the text is a barely distinguishable dark gray
instead of black. I can only read the result with a magnifying glass.

I added "overflow: auto" to the stylesheet for <pre> tags in r63167;
this should give individual scrollbars for code samples not fitting the
page width.
