Nothing. It's a wrong statement, but we'll have to make sure this results
in an error message.

You mean what "matched" would contain? Good question. I think it should be
",hello ", as "world" is specified as the other criterium after the "&". Of
course, if you did the find in "hello world", "matched" would contain a
single space.

"a string" would eat as few characters as necessary to fulfill the
criteria. For "hello" & a string & "world" it would eat as many characters
as are between the first "hello" in the string and the first "world" after
that. The key here is finding the first match. Any subsequent ones need a
chunk expression or some other means to make the "find" command ignore the
start of the sctring passed.

Shouldn't be too hard to make a regexp out of this, I guess. It's like
parsing a string, where "a string" would resolve to a wildcard character
"*". You'd just have to get it to be immediately seen as an expression, it
shouldn't be parsed as a string.
