Hi,

I hit a minor bug with the function org-narrow-to-subtree.

When I narrow to a headline (subtree with just the headline) present
at the end of a file, the last character of the headline isn't present
in the narrowed region. [file1.org and file2.org shown at the end of
the message are examples]

I am attaching a possible patch for the same, but I don't think that
is the "cleanest" way to handle it. Hope it'll help some one else to
fix it in a better way.

Thanks,
Puneeth
