Typo in Rapperswil CWG motion 14

[Dani-Hub]

I noticed a typo in p0542r5,

http://wiki.edg.com/pub/Wg21rapperswil2018/StrawPolls/p0542r5.html

The first edit for

"Modify clause 6.4.1 [basic.lookup.unqual], p. 7:"

has a "contact condition" instead of a "contract condition"

Please check pull request #2151; I can't find "contact" in there.
