It may be beneficial to optionally allow the users to check attributes taken from a commit other than HEAD against paths. Add a new flag `--source` which will allow users to check the attributes against a commit (actually any tree-ish would do). When the user uses this flag, we go through the stack of .gitattributes files but instead of checking the current working tree and/or in the index, we check the blobs from the provided tree-ish object. This allows the command to also be used in bare repositories. Since we use a tree-ish object, the user can pass "--source HEAD:subdirectory" and all the attributes will be looked up as if subdirectory was the root directory of the repository. We cannot simply use the `:` syntax without the `--source` flag, similar to how it is used in `git show` because any non-flag parameter before `--` is treated as an attribute and any parameter after `--` is treated as a pathname. The change involves creating a new function `read_attr_from_blob`, which given the path reads the blob for the path against the provided source and parses the attributes line by line. This function is plugged into `read_attr()` function wherein we go through the stack of attributes files.
