[PATCH v2 0/2] index-pack: fsck honor checks

["John Cai via GitGitGadget" <gitgitgadget@gmail.com>]

git-index-pack has a --strict mode that can take an optional argument to
provide a list of fsck issues to change their severity. --fsck-objects does
not have such a utility, which would be useful if one would like to be more
lenient or strict on data integrity in a repository.

Like --strict, Allow --fsck-objects to also take a list of fsck msgs to
change the severity.

Change since V1:

 * edited commit messages
 * clarified formatting in documentation for --strict= and --fsck-objects=

John Cai (2):
  index-pack: test and document --strict=<msg>
  index-pack: --fsck-objects to take an optional argument for fsck msgs
