[PATCH v2 0/2] Config conditional include

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

Second try. The anchoring rules now look a lot better. I cherry picked
Jeff's skip_prefix_mem() for now to avoid dependency.

There's a surprise about core.ignorecase. We are matching paths, so we
should match case-insensitively if core.ignorecase tells us so. And it
gets a bit tricky if core.ignorecase is defined in the same config
file. I don't think we have ever told the user that keys are processed
from top down. We do now.

It makes me wonder if we should allow users the option to match case
insensitively regardless of filesystem too. Something close to
pathspec magic. But that probably has little use in real world for a
lot more work.

The '/' vs '\\' battle on Windows, I'll leave it to Windows guys again.

I'm also not adding "worktree:" condition. If that happens, it
probably happens in the per-worktree config file series.

To leave room for future expansion, perhaps we should declare that ':'
can't appear in the pattern, so we can add more prefix later, and even
stack them, e.g. "regexp:gitdir:<pattern>". The prefix can't be one char
long. That should be enough for windows to specify full path
including the drive letter.
