🚀 go-pugleaf

Whilst perusing the length lists of variables, I came across this gem.  I'd
wanted functionality similar to this, but not enough to actually program it.

That is, you know how the current column is usually preserved when moving
between lines?  This is called the goal column.  Setting track-eol makes it so
that when you explicitly move to the end of a line, the goal column essentially
becomes infinite.

But after having tried it, I discover that explicitly moving to the beginning
of an empty line does not reset it.  I find this behavior non-intuitive and
user-error-prone.  Note that the feature is disabled by default.  Opinions?

Followups to comp.emacs.
