The Vimscript use a wrong regex sample

[uudicet]

In the line 112-118.
The sample put the pattern and string in wrong place, so the match test always false, the unmatch test always true.
I think the follow is better:

echo  "hello" =~  "He"    | " Regular expression match, uses 'ignorecase'
echo  "hello" =~# "He"    | " Regular expression match, case sensitive
echo  "hello" =~? "He"    | " Regular expression match, case insensitive
echo  "hello" !~  "He"    | " Regular expression unmatch, use 'ignorecase'
echo  "hello" !~# "He"    | " Regular expression unmatch, case sensitive
echo  "hello" !~? "He"    | " Regular expression unmatch, case insensitive
