vi: fix word operations across line boundaries
Commit 4b49422a0 (vi: fix changes to word at end of line. Closes
11796) fixed a problem where an operation on a word at the end of
a line followed by a line starting with whitespace incorrectly
joined the lines. However it also broke the case where operating
on multiple words across a line boundary *should* join the lines.
Fix this by detecting when trailing whitepace in a word operation
includes a newline. Whitespace beyond the newline is excluded
from consideration.
