In the PDF output, TeX adds more spacing after an end-of-sentence
period.  After an abbreviation however, you don't want that larger
space.  Writing e.g.@: gets TeX to only add normal spacing.
See 'info texinfo "Not Ending a Sentence"'.

It's a very minor nit.  But since we fixed all instances of 'e.g.'
and 'i.e.' for the 4.5 release, it would be nice to not regress.
