Since there is no bug in Emacs, I'm closing this. Feel free to reopen if
you believe there's still something open to fix.

[Message part 4 (text/plain, inline)]

Starting M-x shell and afterwards entering "mosh mymachine" results into
mosh crashing with:

mosh-server: terminalframebuffer.cc:73:
Terminal::Framebuffer::Framebuffer(int, int): Assertion `s_height > 0'
failed.

I suspect that the window height is not being exposed in a standard
terminfo way to be consumed by mosh.

Furthermore escapes from bash and zsh are displayed as

[16:58] wurzel:~% [?2004

(where wurzel is my hostname and 16:58 is the time)
