In [re.regiter.cnstr]-28.12.1.1/2 the effects paragraph starts with:

"Effects: Initializes begin and end to point to the beginning and the
end of the target sequence, sets pregex to &re, sets flags to f,[..]"

There are two issues with this description:

1) The meaning of very first part of this quote is unclear, because
there is no target sequence provided, instead there are given two
parameters a and b, both of type BidirectionalIterator. The mentioned
part does not explain what a and b represent.

2) There does not exist any parameter f, but instead a parameter
m in the constructor declaration, so this is actually an editorial
fix.

Proposed resolution:

In 28.12.1.1/2 change the above quoted part by

"Effects: Initializes begin and end to point to the beginning and the
end of the target sequence designated by the iterator range [a, b),
sets pregex to &re, sets flags to m,[..]"
