Incorrect Upper Bound in POSIX "graph" Character Class Definition

[c000]

I noticed that the current definition of the POSIX "graph" character class is written as:

regex-tdfa/lib/Text/Regex/TDFA/Pattern.hs

Line 204 in 0392ea0

"graph" -> ['\41'..'\126']

According to the Wikibooks: Regular Expressions - POSIX Basic Regular Expressions, the [:graph:] character class is equivalent to [^ [:cntrl:]].
So "graph" class should cover characters from decimal 33 through 126.
