Syntax page short on detail for \b #32

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
http://code.google.com/p/re2/wiki/Syntax describes the zero-width assertions \b 
and \B.

"\b  at word boundary (\w to left and \W to right or vice versa)"

Should this documentation be expanded to explain what happens at the start or 
end of a line/string?  E.g. the end is treated as \W.  It would be nice if this 
bit of re2's behaviour was documented.
