Did you know that 'fetch' and 'pull' read the index? I didn't, or this would
have been an integration much earlier in the cycle. They read the index to
look for the .gitmodules file in case there are submodules that need to be
fetched. Since looking for a file by name is already protected, we only need
to disable 'command_requires_full_index' and we are done.

The 'ls-files' builtin is useful when debugging the index, and some scripts
use it, too. We are not changing the default behavior which expands a sparse
index in order to show all of the cached blobs. Instead, we add a '--sparse'
option that allows us to see the sparse directory entries upon request.

Updates in v2
=============

 * Rebased onto latest ld/sparse-index-blame without issue.
 * Updated the test to use diff-of-diffs instead of a sequence of greps.
 * Added patches that remove the use of 'test-tool read-cache --table' and
   its implementation.


Updates in v3
=============

 * Fixed typo in commit message.
 * Added comments around doing strange things in an ls-files test.
 * Fixed adjacent typo in a test comment.


Updates in v4
=============

 * Rebased on to 'master' now that ld/sparse-index-blame is merged.
 * Change testing strategy to check exact output instead of using 'diff -u'.
 * Updated documentation to state that directories have a trailing slash.

This version looks good to me:
