Avoid visible ~ in pdf documents (such as Figure~1)

The invisible space marker "~" was visible due to a
texi2dvi bug. This was most visible in legends like "Figure~1",
where "~" was added by LaTeX. Most (or all) self-made
instances of "~" were already removed or replaced with "\;".
It seems that (unnecessary) \usepackage[english]{babel} fixes
this issue.
