lynx-dev Transport links between bookmark files... Here's the code

[mattack]

I've never done this before (or even used diff much), so please inform me
about what I'm doing wrong, while hopefully not blowing my idea out of the
water..

So, basically:

When you are viewing a bookmark file, you can hit 't' to transport the
current link to another bookmark file.  I have covered the error cases
I could think of, and tried edge cases (first link, last link).  It even 
allows a lame way to very slowly reorder your links within one bookmark
file (though you must have multibookmark mode on) by selecting the same 
file...  It'll move that bookmark to the end.

I'm based upon
Lynx Version 2.8.3dev.2 (18 Jun 1999)
