doc: Use @: where needed

When an abbreviation ends with a dot followed by whitespace, Texinfo
thinks the dot ends a sentence, and applies spacing rules etc. based
on that.  To prevent this, there is the @: macro.

This patch puts @: after every vs., e.g., and i.e. where it is needed.
In a few cases there was "@ " already, or "@\n", but @: is slightly
better, and more consistent.

	followed by whitespace.
