core: fix execution of multiple commands separated by newline when there are no spaces

For example typing this on core buffer:

/t1
/t2

was not executing the two commands but sent the text to the buffer instead.

This is because WeeChat thinks it's a path, and the newline should indicate
it's not (like a space before the next slash: "/t1 /t2" is a command, not a
path, but "/t1/t2" is considered a path).
