That's by design. You asked for the entries in a specific file, and we
do not follow any includes by default in that case. You can use
`--include` if you want to follow includes.

The documentation is quite misleading here, though. Here's a patch.

Subject: git-config: better document default behavior for `--include`

As described in the commit message of 9b25a0b (config: add
include directive, 2012-02-06), the `--include` option is
only on by default in some cases. But our documentation
described it as just "defaults to on", which doesn't tell
the whole story.
