Copying (Left-Drag, Right) in WSL gives 128 spaces instead of a blank line

Probably a dup; I couldn't find it.

If, in WT, I copy (Left-Drag, Right), as pictured,

and paste into notepad, I get what's expected (no extra stuff).

If I do the same in WSL

and paste into notepad, I get (this is hard to picture)

On the line immediately after the second "foo" there are 128 (terminal width) spaces followed by the next prompt; there is not a blank line.

There has been no comment so I tried it again. The result was the same. Copying several lines (which include a blank line) in WSL and then pasting into notepad results in 128 spaces (my terminal width) where the blank line was, and no newline. I tried this using both bash and tcsh in WSL with the same undesirable result. It does not happen when I do the same experiment in a Windows shell.

Most of the team was out on vacation over the holidays. What shell are you using? If it's bash, can you try launching a nested shell with env -i bash --norc --noprofile and then try executing echo and copying the results?

That works OK. In fact, I can't get it to screw up in bash now. But in tcsh, it's as described. In both shells, I used printf "foo\n\n" to test.
