Nope, I believe you. It does not go this way. Please revert the previous
patch.

Let's assume, the default shell in OpenSolaris is buggy. It's not the
first time, Tramp is confronted by this. Consequently, we shall use
another shell like bash, instead of applying several workarounds for
those bugs. The appended patch does exactly this. Note that I couldn't
test it with a remote OpenSolaris machine ...

Before you test this, you must call "M-x tramp-cleanup-all-connections".
This flushes Tramp's caches, which is necessary.
