Ah, so this comes from the --remote call.

Interesting, that the :norm4 works, because there is no pipe after it.
But it looks like Vim builds up the whole string dynamically and adds an
'|' at the end automatically.

However, I think this silently breaks, because the ":norm" sees
everything after it as belonging to it, so in this case the '|' does not
really end the user specified command and therefore you see this
message. I messed around briefly, trying to wrap everything into an :exe
expression (or using :call cursor), but at least, this did not seem to
work on my windows environment.

A possible work-around would be to it build the whole command yourself
by using, e.g. --remote-send "<c-\><c-N>:e +3|norm4| .bashrc<cr>"

or:

--remote-send "<c-\><c-n>:e .bashrc<cr>|:e|norm4|<cr>"

I wonder if this would work better with the following patch, by wrapping everything into an :exe call.

diff --git a/src/clientserver.c b/src/clientserver.c
index bb2108d7d..c4489c953 100644
