Actually, the description of E10 says it is _often_ caused by
command-line continuation; it does not say that that is the only
cause.

I played with this a little bit before seeing Gerald's reply and
discovered, as he pointed out, that the problem is with the '|'. I
worked around it by adding backslashes until it worked. I found I
had to escape the first one in the pattern to avoid the error, then
figured I would have to escape the second one twice to make vim see
it as '\|'.
nmap <space> :let
@a=substitute(getline('.'),'\(^.*\|\s*\)\\|\(\s\s*$\)','','g')<CR>
And as Gerald said, it needs a "<CR>" at the end, too.

Now that I know what you intended this to do, I tested my version
and it seems to work.
I wish I had a better understanding of when vim ignores quotes and
instead requires backslashes to escape |'s.
