The issue is the pushback on text files (which readChar does not use).
I've altered the logic in 2.7.2 patched so that seek() clears the
pushback.
NB:
1) Your code is incomplete (you need library(MASS)),
2) You are asked not to report on obsolete versions of R.

This is a different issue, and one that I am unable to reproduce. If I
start PUTTY with X11 forwarding and no X server, I get the usual message
from X11().
As I understand it, when running available.packages() you are getting a
call to the tcltk version of chooseCRANmirror(). Again that work
