Make wrap=FALSE by default

[yihui]

so that we can retire Roxygen: list(wrap = FALSE) in DESCRIPTION. Is this going to happen some day?

Or at least make it configurable as an argument in roxygenize().

Yes, the plan is to do this gradually.

I have sent a PR to expedite this :)

I now think we don't need to be so cautious - I think we can just print a message describing what is happening (i.e. wrap value taken from DESCRIPTION Roxygen: list(wrap = TRUE)) and then change the default to FALSE.
