[PATCH] Perldoc.pm tweak for VMS

When placing the configured paging program at the head of its list of 
possible pagers, lib/pod/Perldoc.pm uses the -x file test to see if the 
program can be run by the current process.  This test generally fails on 
VMS because $Config{pager} is by default a command and not a file.  The 
patch below gets us our configured pager back by skipping the file test 
on VMS.


This is against perl-5.8.x@18953.
