Title: remove the first '/' in path

support we have the following directory structure:

root/
a/
a.cc
b/
b.h

and in a.cc, we include b.h

#include "b.h"

and in the original implementation, it would be changed to

#include "/b/b.h"

this is because `${hdr_path#$root}` operation is incomplete for this scenario:

hdr_path = "/root/b/b.h"
root = /root"
