tests: (no-eol) markup for command output without trailing LF stable

tests: (no-eol) markup for command output without trailing LF

Output chunks without a trailing LF will now work but get (no-eol) appended.

This change mostly moves code around so we can handle that an output line
starts with data from previous command, followed by salt and the next command.
