The general rule is "one patch for one thing".  In this case, "one thing"
would be "fix braces" across an entire .c file (which meant that if there were
5 or 10 "if" statements that needed fixing in foo.c, you'd submit one patch
that fixed all of them.  But a patch that fixed leading tabs/blanks issues or
too-long line issues would be a separate patch.

So you'd want (B).
