Tramp SSH method hangs after "found remote shell prompt"

Tramp SSH method hangs after "found remote shell prompt"

[dnquark]

I am running Windows; Tramp used to work with Emacs 23.1, provided
emacs was launched from cygwin shell and inherited the cygwin
environment.  It broke in Emacs 23.2.  Can someone tramp-savvy take a
peek at the debug output and help me figure out what's going on?...  A
few suspicious things: Tramp wants to use cmd.exe; somehow it fails to
bring up the local shell when I try to set tramp-encoding-shell to
bash.exe.  Not sure if that matters.  In addition, the default ssh
method gives an error  "bash: no job control in this shell".  However,
using sshx method (which starts ssh with a -t flag and avoids this
error) makes Tramp hang in the same exact place.

Here are some relevant parts from the debug log:

.....and this is where it hangs.
