[Spacewalk-list] Spacecmd - strangeness on piping

[Parsons, Aron]

Python allowed a fairly elegant solution.  Fixed in 90b55fb528bfd7b00556445010dea62a22f58899.

% Where does that strange string "^[[?1034h" come from? It's pretty % consistent across all pipes of spacecmd that I'm using, % and its quite irritating, since I haven't been able to discover the why, % where, and hms? about it.

Hi Jonathan,
It's probably readline library leaking terminal escape sequence to stdout.
See https://bugzilla.redhat.com/show_bug.cgi?id=304181.
I'm not sure how to fix / workaround it.
