Make the patch -x option (only enabled with CONFIG_DEBUG) provide more information about why a patch didn't apply. (Offset of first nonmatching character at each line during seek phase.)
Patch from William Haddon to make xargs with blank input call its command line once. (Tweaked slightly for whitespace and to collate variable declarations.)
Cleanup vconfig.

Give xstrncpy() a more informative error message.
Sceond cleanup pass on vconfig
