Encode invalid XML characters instead of skipping them.
The <sp> element in <programlisting> has a new optional attribute
`value`, which contains value of given invalid ASCII character. In
case of space, the `value` attribute is omitted.
Use cases for this: including snippets of *very esoteric* languages,
markup that makes use of the advanced ASCII formatting characters or
for example highlighting a console output containing ANSI color codes
(which is my case, in fact).
Regarding backwards compatibility -- as files with such ASCII
characters are very rare, I don't expect this minor difference in the
output to be a problem. Besides that, such ASCII characters are often
replaced by a space in many applications anyway.
A test snippet was extended to contain a special character so this
difference in behavior could be verified.
