Comment 2 for bug 459185

John is right on all points but one: it's not a specific TERM that is needed but a specific mode.
Namely, shelve works right in an eshell buffer but can't work in regular shell buffer.

Fixing that is not trivial but there is little incentive to do so because 'bzr shelve --all' is
nearly all that is not covered by a judicious combination of diff-mode
 (in a buffer containing the output of 'bzr dif' ) and 'bzr revert' and
'bzr shelve --all' works fine in all shell buffers.
