check_dir Indicates that UNC Paths Do not Exist

[wsloand]

When working on a UNC share, check_dir indicates:

"Error: Can't find directory /server\share\directory\subdir"

This is the simplified path. It appears likely related to the following code in check_dir:

x <- gsub("\", "/", x, fixed = TRUE)

\ (or "\") is the beginning of a UNC path. Since the current version of devtools requires R >=3.1, perhaps you can use the new functionality in file.path to strip the trailing space and swap that line for

x <- file.path(x)

I think I can just remove gsub("\\\\", "/", x, fixed = TRUE) - it looks like it has too much escaping anyway.
