But still the tramp-rsh-end-of-line docs say that it shouldn't be changed normally, perhaps a remark that it might be necessary with plink would be nice. I don't know how often this is needed with plink, but if it's more or less common, you should perhaps add paragraph to your manual. At first it really didn't look that tramp-rsh-end-of-line was the source of the problem. I tried playing with the tramp-shell-prompt-pattern, because I thought that's why the prompt isn't recognized. Then I thought tramp-open-connection-setup-interactive-shell inserted an adiditional \n somewhere, from there I dug into tramp-send-command-internal, where I finally found tramp-rsh-end-of-line. Long story short: It's not obvious to change tramp-rsh-end-of-line, so a remark somewhere (aside from the documentation of a variable I didn't even bother to look at in the beginning) would be nice.
