commit 6a8e5dbbeb3644d733e5e6acb0f5d19280d1c647
from: Stefan Sperling <stsp@stsp.name>

tweak the error message shown by 'got send' when ancestry has diverged

The previous message steered users towards rebase; nowadays we also have
a merge command and send -f. It's tricky to explain all possibilities of
what to do next in a single line, but this is probably better than nothing.
