[blush... *BLUSH* ...
I didn't look at sys.source();
just knew that parts of it used to look rather "magical" to me ..
Of course we now could even make
keep.source = getOption("keep.source")
an argument to library(), being propagated to sys.source(..).

would be nice if it *was* configurable for base as well;
possibly both via cmd line option
(something like --keepsource / --no-keepsource )
and a setting in Rprofile..
