[Bug-wget] Clang analyze on Win32

[Gisle Vanem]

I'm trying to familiarize myself with clang and did a
quick 'clang-cl --analyze <MSVC-CFLAGS> <SOURCES>'. This is what
it revealed:

init.c(569,13) :  warning: Value stored to 'home' during its initialization is 
never read
     char *home = home_dir ();
            ^~~~   ~~~~~~~~~~~

Makes sense since since:
   char *home = home_dir ();  << line 569
   xfree (file);
   home = ws_mypath ();

Seems this last line should be dropped since home_dir() already
calls ws_mypath(). So I think this patch is in order:

--- a/init.c    2015-05-25 18:36:26 +0000
+++ b/init.c      2015-06-17 22:26:34 +0000
