Fix bugs in clang-format and tab configure

clang-format maybe not exist on some environment, so it's necessary to
use default gg=G format. Besides, clang-format should use currect style
file to work but not just `clang-format` command by default, because it
will use .clang-format from the curreent dir but not the dir the file is
in.

And, maybe some other config affect tab set, tab is expanded in
shell/make/vimscript, which is not my mean. Now it's fixed.
