[R] months not working with local language (weekdays does)

[Duncan Murdoch]

For what it's worth, I tried setting my Region | Formats setting to 
Spanish (Peru) in Windows 10 Control Panel, and got Spanish weekday and 
month results.

I believe on Windows we use the Microsoft C strftime function to produce 
these strings, with the %A (for weekday) or %B (for month) formats.  So 
this question probably needs to be addressed to Microsoft.
