* 'jc/maint-1.6.0-blank-at-eof' (early part):
diff --whitespace: fix blank lines at end
core.whitespace: split trailing-space into blank-at-{eol,eof}
diff --color: color blank-at-eof
diff --whitespace=warn/error: fix blank-at-eof check
diff --whitespace=warn/error: obey blank-at-eof
diff.c: the builtin_diff() deals with only two-file comparison
apply --whitespace: warn blank but not necessarily empty lines at EOF
apply --whitespace=warn/error: diagnose blank at EOF
apply.c: split check_whitespace() into two
apply --whitespace=fix: detect new blank lines at eof correctly
apply --whitespace=fix: fix handling of blank lines at the eof
