it gives a warning.

* js/clean-report-too-long-a-path:
  clean: show an error message when the path is too long

"git push --atomic" that goes over the transport-helper (namely,
the smart http transport) failed to prevent refs to be pushed when
it can locally tell that one of the ref update will fail without
having to consult the other end, which has been corrected.

* es/local-atomic-push-failure-with-http:
  transport-helper: avoid var decl in for () loop control
  transport-helper: enforce atomic in push_refs_with_push

Code clean-up for new compilers.
The 'kwset' one may get a wholesale replacement, either with new
version of kwset from upstream or removal of its users, but in the
meantime, it is probably OK to merge it down.

  config: avoid calling `labs()` on too-large data type
  winansi: simplify loading the GetCurrentConsoleFontEx() function
  kwset: allow building with GCC 8

  clang-format: use git grep to generate the ForEachMacros list

The URL decoding code has been updated to avoid going past the end
of the string while parsing %-<hex>-<hex> sequence.

* md/url-parse-harden:
  url: do not allow %00 to represent NUL in URLs
  url: do not read past end of buffer

The description about slashes in gitignore patterns (used to
indicate things like "anchored to this level only" and "only
matches directories") has been revamped.

* an/ignore-doc-update:
  gitignore.txt: make slash-rules more readable

The filter_data used in the list-objects-filter (which manages a
lazily sparse clone repository) did not use the dynamic array API
correctly---'nr' is supposed to point at one past the last element
of the array in use.  This has been corrected.

* md/list-objects-filter-memfix:
  list-objects-filter: correct usage of ALLOC_GROW

"git fetch" into a lazy clone forgot to fetch base objects that are
necessary to complete delta in a thin packfile, which has been
corrected.

* jt/partial-clone-missing-ref-delta-base:
  t5616: cover case of client having delta base
  t5616: use correct flag to check object is missing
  index-pack: prefetch missing REF_DELTA bases
  t5616: refactor packfile replacement

When creating a partial clone, the object filtering criteria is
recorded for the origin of the clone, but this incorrectly used a
hardcoded name "origin" to name that remote; it has been corrected
to honor the "--origin <name>" option.

* xl/record-partial-clone-origin:
  clone: respect user supplied origin name when setting up partial clone

"git request-pull" learned to warn when the ref we ask them to pull
from in the local repository and in the published repository are
different.

* pb/request-pull-verify-remote-ref:
  request-pull: warn if the remote object is not the same as the local one
  request-pull: quote regex metacharacters in local ref

"git p4" was not properly quoted to protect a caret and running a
broken command on Windows, which has been corrected.

Update to Unicode 12.1 width table.

The data collected by fsmonitor was not properly written back to
the on-disk index file, breaking t7519 tests occasionally, which
has been corrected.

* js/fsmonitor-unflake:
  mark_fsmonitor_valid(): mark the index as changed if needed
  fill_stat_cache_info(): prepare for an fsmonitor fix

"git merge --squash" is designed to update the working tree and the
index without creating the commit, and this cannot be countermanded
by adding the "--commit" option; the command now refuses to work
when both options are given.

* vv/merge-squash-with-explicit-commit:
  merge: refuse --commit with --squash

"git bundle verify" needs to see if prerequisite objects exist in
the receiving repository, but the command did not check if we are
in a repository upfront, which has been corrected.

* js/bundle-verify-require-object-store:
  bundle verify: error out if called without an object database

"git am -i --resolved" segfaulted after trying to see a commit as
if it were a tree, which has been corrected.

* jk/am-i-resolved-fix:
  am: fix --interactive HEAD tree resolution
  am: drop tty requirement for --interactive
  am: read interactive input from stdin
  am: simplify prompt response handling

The server side support for "git fetch" used to show incorrect
value for the HEAD symbolic ref when the namespace feature is in
use, which has been corrected.

* jk/HEAD-symref-in-xfer-namespaces:
  upload-pack: strip namespace from symref data
