@words[] give wrong results if first word is quoted

[Anton Monroe]

@word and @words are smart enough to recognize a quoted string as one word, but @words gets seriously confused if the first word is quoted. For instance, it says that

"one" two three four five six

has 5 words. But it is stranger than that. Capitalization changes the word count--

"ONE" two three four five six

has 1 word.

"One" two three four five six

has 3 words.
I can't imagine how that is possible, but it is what I see.

A workaround is to explicitly set the word separator, as in

@words[" ",%string]

@word does not show the problem. It parses the string correctly in all cases.

Attached is a batchfile that should demonstrate it.

I get the same results from 4OS2 versions 3.09 and 3.11.
