There's another mis-feature of ^A in tip (4.2 version, at least): in
addition to being the default raisechar, it is also tip's mark for
its own internal escape sequences, used for %take. We discovered it
here the hard way, when trying to move files using a tip within a tip -
the upstream tip swallowed the ^A's meant for the downstream tip's echo
command, so that the latter didnt know when the file ended and got stuck,
and to top that, when we finally managed to kill it, the former had put us
in upper-case mode - on a line that wasn't expecting that!

(If you know how tip works internally, you can figure out what happened,
otherwise, don't bother trying).
