Setting the variable instead of wrapping getenv has the additional benefit that it also affects child processes (read: scripted commands).

...all of these also do the string concatenation correctly (i.e. not "C:/\Users\MyName" as this patch does), fall back to %USERPROFILE% if %HOMEPATH% is not set, and most (except git-wrapper) even check that the directory exists. So IMO this patch has been superseded by more robust solutions and should be dropped.
