Previous round is at <20181209200449.16342-1-t.gumme...@gmail.com>.
Thanks Junio, Duy and Elijah for your comments and suggestions on the
previous round.
This round drops the last three patches from the previous round,
namely introducing a "--cached" and a "--ignore-unmatched" option, and
using the new no-overlay mode in "git stash". The --ignore-unmatched
option may not be necessary, while using the new mode in 'git stash'
will be done once the stash-in-C topic landed.
Introducing a --cached and --worktree-only (as suggested by Elijah)
option can come in a future step, they are orthogonal to this topic.
Other changes from v1:
- Rebase onto the current master, so we can also move t2028 and t2029
to the t24xx range.
- Add a comment clarifying why using the CE_WT_REMOVE flag and topath
in checkout_entry is a bug.
- clarify a comment in checkout.c
- factor out the function to mark a cache entry as CE_MATCHED, and
have separate such functions for overlay mode and no-overlay mode.
This should hopefully make the logic a bit easier to follow.
- Adjust the commit message, justifying why we don't remove untracked
files even in the new no-overlay mode.
- add documentation for the new feature
- document that -p defaults to no overlay mode, and cannot be used
with overlay mode.
- add a config option checkout.overlayMode, so overlay mode can be
turned on by default.
Range-diff can be found after the diffstat.

'git checkout --overlay -p' to avoid confusing users who would expect
to be able to force overlay mode in 'git checkout -p' this way.
