Allow line breaks within \verb and verbatim output
Description
LaTeX's \verb macro treats its argument as an unbreakable unit
of text. This can lead to poor typesetting, especially when the
argument is long. The spverbatim package provides an \spverb
macro that is analogous to \verb and an spverbatim environment
that is analogous to verbatim with the difference being that
\spverb and spverbatim allow LaTeX to break lines at space
characters.
