Yes, it's there. Probably it's for filenames which contain shell
meta characters like "*" or just plain spaces. By quoting vi ensures that
the filename is "correctly" interpreted by the shell. Most people, like
me, never notice such a thing, because they have plain sh or csh.
I think when vi was written, there was no such thing as a "8 bit" shell.
Can you come up with a fix ?
