Re: [PATCH 2/5] git-submodule: New subcommand 'summary' (2) - hard work

I think you would want to read full 40-char sha1_src and
sha1_dst with "while read", and keep that full 40-char in these
variables, and use them when calling rev-parse here.

Hmm, precision is really a problem. However, "git diff --raw" will not
always give full 40-char sha1, instead it will give sha1 with enough
length. So maybe i can use the sha1 from "git diff --raw" ?

Oh, I'm wrong. It seems 'git diff --raw' will always give full 40-char
sha1 for submodule entry and abbreviated sha1 for blob entry.
