Hi Michael,

I think keeping tests as separate as possible is a good idea.
Looking at the patch https://public-inbox.org/git/20180413094314.GA2404@bod/

The patch seems reasonable, apart from minor nits:
In the test we'd prefer no whitespace on the right side of the redirection,
i.e. echo content >foo

Instead of evaluating git commands in shell and assigning it to a variable,
we'd prefer to dump it to files:

  git show HEAD:symlink >actual &&
  echo foo >expect &&
  test_cmp expect actual

(instead of content=$(git show HEAD:foo) && test $content == ...)

The reason for this is that the &&-chain will inspect the return code
of the git command.

There is a typo &e&.

Can we reword the documentation, such that we do not have
an occurrence of "extended SHA-1" ?
(By now the Git community came up with a plan to migrate
away from SHA-1, hence we'd not want to introduce more
dependencies even in the form of documentation for that)


Follow symlinks inside the repository when requesting
objects in extended revision syntax of the form tree-ish:path-in-tree.
