Unless explicitly requested to be so, most likely it is indeed meant
to be without the semicolon, i.e. "C:\\Users\\Ben/R/win-library/2.12"
(or "normalized" "C:\\Users\\Ben\R\win-library\2.12", but that doesn't
matter here).  This is in line with what is said in help(".libPaths"):

"By default R_LIBS is unset, and R_LIBS_USER is set to subdirectory
‘R/win-library/x.y’ of the home directory, for R x.y.z."

Here are my Windows environment variables:

> Sys.getenv("R_LIBS_USER")
                       R_LIBS_USER
"C:\\Users\\hb/R/win-library/2.12"

> Sys.getenv("HOME")
           HOME
"C:\\Users\\hb"

There should certainly not be any semicolons in the latter.  If you
set HOME to "C:\\Users\\hb;" before starting R, you do get:

> Sys.getenv("R_LIBS_USER")
                        R_LIBS_USER
"C:\\Users\\hb;/R/win-library/2.12"
