[ESS] package loads without my request

[Paul Johnson]

Today, I see a new problem I did not see before. It may have been like
this all along, but I don't like it.  If this is supposed to happen, I
wonder what it is called and how to avoid it.

The problem is that when I load a function in an R file that is in a
package source code directory, something in ESS causes the package to
be loaded when the function is read into R.

The package gets loaded if I read in a function with the "Eval
Function" button, or if I highlight a function and choose "Eval
Region".  It also happens if I hit the "Load File" button or cursor
into a function and hit C-c C-c.

The package does not load if I put cursor at top of a function and
send each individual line to the session.  This would be acceptable,
except that hitting next a few 100 times is boring.

I don't want the package to load, I'm trying to fix a problem in it by
editing the R files. If the package loads, then the functions in the
package become available and they frustrate my effort to fix the R
files.

Then I noticed that if I copy the R file into another folder, "/tmp"
in this case, then I'm able to open the file in Emacs and the package
never loads itself without my explicit request to do so. Hence, I
conclude Emacs/ESS are noticing that I'm in a package directory and
I'm getting an intended behavior.

Turning off "Developer mode" in ESS does not change this.

This is Ubuntu Emacs 24.5.1 with ESS 16.10. Here I notice I'm back in
that same confusing situation where the system's ESS 16.10 is used,
but in my ~/.emacs-d I have a newer MELPA version, but Emacs does not
notice it.  I'll leave that as a problem for another day.
