Fix SF bug #1402308, segfault when using mmap(-1, ...)
This didn't crash on Linux, but valgrind complained.
I'm not sure if this test is valid on Windows.
initscr() will exit if there's an error. Try to catch the obvious failure
cases if TERM isn't set or is unknown (perhaps we should only check if
unset or empty?)
Skip the test if TERM isn't set. This seems to occur when running under
buildbot and presumably cron.
For some more info check here:

SF patch #1364545: test_cmd_line.py relied on english error messages when
invoking the Python interpreter (which didn't work on non-english Windows
versions). Check return codes instead.
Fix SF bug # 1330039, patch # 1331635 from Lars Gustaebel (tarfile maintainer)
Problem: if two files are assigned the same inode
number by the filesystem, the second one will be added
as a hardlink to the first, which means that the
content will be lost.
The patched code checks if the file's st_nlink is
greater 1. So only for files that actually have several
links pointing to them hardlinks will be created, which
is what GNU tar does.
