[PATCH v2 0/1] builtin/blame.c: bit field constants into bit shift format

we are looking at bitfield constants, and elsewhere in the Git source code, such cases are handled via bit shift operators rather than octal numbers, which also makes it easier to spot holes in the range (if, say, 1<<5 was missing, it is easier to spot it between 1<<4 and 1<<6 than it is to spot a missing 040 between a 020 and a 0100). Also, bit shifts lead to low-level optimizations because they require fewer calculations for the CPU.

Special Thanks to @dscho for helping me out throughout the process.
