I hope it's enough to help reproduce the bug. I only see a problem with wrapping on the line containing "xterm zsh upnet" which does the wrong thing at the "p" in "offlineimap". Rendering the file, I see this (all characters are printable, I'm showing the full line): \n \E(0^Ox \E(B \E(0^Ox \E(B \E(0^Otq \E(B4*[xterm \E(0^Oqqq \E(Bzsh] \n \E(0^Ox \E(B \E(0^Ox \E(B \E(0^Otq \E(Bxterm \E(0^Oqqq \E(Bzsh \E(0^Oqqq \E(Bupnet \E(0^Oqqq \E(Bmovemail \E(0^Oqqq \E(Bofflineimap \E+ \n Note the "\E+". That's an error (in psmisc, since it has no reason to generate something like that). There's no such escape sequence. That is, not as you see it. \E+ followed by a final character looks like this in ctlseqs.ms: ESC + C Designate G3 Character Set (ISO 2022) Final character C for designating character sets (0 , A and B apply to VT100 and up, the remainder to VT220 and up): C = 0 -> DEC Special Character and Line Drawing Set C = A -> United Kingdom (UK) C = B -> United States (USASCII) C = 4 -> Dutch C = C or 5 -> Finnish C = R -> French C = Q -> French Canadian C = K -> German C = Y -> Italian C = E or 6 -> Norwegian/Danish C = Z -> Spanish C = H or 7 -> Swedish C = = -> Swiss (this doesn't apply if you're in UTF-8 mode by the way). A correctly behaving terminal will allow some control characters in the middle of the sequence, so the newline gets through. But when it hits a noncontrol character such as space, it terminates the sequence (eats the characters). I don't see the \E+ explicitly in pstree.c - it's most likely some trash that it's producing in out_char as I noted in my first response. -- Thomas E.
