[ESS-bugs] ess-mode 5.4; R help fails in inferior R processes running under ESS 5.4 with Gnu Emacs 23.1 under MS Windows XP.

[Steve Gutreuter]

Calls to help usually (but not always) fail from inferior R processes
in my laptop installation of ESS 5.8 + Gnu Emacs 23.1 running under
Windows XP.  The error messages are always something like:

starting httpd help server ... done
Error in shell.exec(url) :
  access to 'http://127.0.0.1:20121/library/base/html/array.html' denied

 Oddly, it sometimes works and I have not been able to find a pattern
for the failures.
