Here's a simple reproducible bug - something unexpected in sparse-checkout mode:
$ git clone git@github.com:jekyll/jekyll.git --no-checkout
Cloning into 'jekyll'...
remote: Counting objects: 41331, done.
remote: Compressing objects: 100% (5/5), done.
remote: Total 41331 (delta 0), reused 0 (delta 0), pack-reused 41326
Receiving objects: 100% (41331/41331), 11.91 MiB | 7.98 MiB/s, done.
Resolving deltas: 100% (26530/26530), done.
$ cd jekyll
$ ls
$ git config core.sparsecheckout true
$ echo 'docs*' > .git/info/sparse-checkout
$ git read-tree -mu HEAD
$ ls
docs rake
I didn't expect to see 'rake' amongst the results.
If I take out the asterisk on the echo line, only 'docs' is checked
out after the read-tree operation. Even if asterisk isn't allowed, I'd
not expect it to fail in that way. Sparse checkout documentation is a
little . .. . sparse it has to be said (sorry).
As it happens, I have some more complicated cases where
sparse-checkout is doing the wrong thing in the working copy - and
I'll work towards reproduction of that/those after this. Best to start
with a simple reproducible case in case there's a simple fix for more
that one similar bug.
Regards,

If you look inside the rake/ directory, you should see that only
"docs.rake" was checked out.
The sparse-checkout file uses the same parser as .git/info/exclude. One
important aspect of that file is that entries are _not_ left-anchored
unless they start with "/". So you asked Git to include files named
"docs*" anywhere in the tree.
You probably wanted just:
echo /docs >.git/info/sparse-checkout

Related bug (maybe the same). Reproduction:
$ git clone git@github.com:jekyll/jekyll.git --no-checkout
Cloning into 'jekyll'...
remote: Counting objects: 41331, done.
remote: Compressing objects: 100% (5/5), done.
remote: Total 41331 (delta 0), reused 0 (delta 0), pack-reused 41326
Receiving objects: 100% (41331/41331), 11.91 MiB | 9.15 MiB/s, done.
Resolving deltas: 100% (26530/26530), done.
$ cd jekyll
$ git config core.sparsecheckout true
$ echo 'CONDUCT.markdown' > .git/info/sparse-checkout
$ echo 'Gemfile' >> .git/info/sparse-checkout
$ echo 'Rakefile' >> .git/info/sparse-checkout
$ echo 'appveyor.yml' >> .git/info/sparse-checkout
$ git checkout --
Your branch is up-to-date with 'origin/master'.
$ ls
CONDUCT.markdown Gemfile Rakefile appveyor.yml lib
I was not expecting to see 'lib' in the resulting file list
I didn't say so before - I'm on a Mac, with a homebrew installed Git 2.11.0

Yep, I think this is the same problem. Inside lib, you get only
"lib/theme_template/Gemfile", because it matches your unanchored
pattern. Using "/Gemfile" in the sparse-checkout file fixes it.

Well I feel a bit silly. Thanks for responding.
