Our documentation used to assume having files in .git/refs/*
directories was the only to have branches and tags, but that is not
true for quite some time.

Not urgent (non regression).

  Documentation: do not mention .git/refs/* directories

Merge branch 'jc/maint-protect-sh-from-ifs' into pu

When the user exports a non-default IFS without HT, scripts that
rely on being able to parse "ls-files -s | while read a b c..."
start to fail.  Protect them from such a misconfiguration.

* jc/maint-protect-sh-from-ifs:
  sh-setup: protect from exported IFS
Merge branch 'jk/docs-docbook-monospace-display' into pu

The documentation in the TeXinfo format was using indented output
for materials meant to be examples that are better typeset in
monospace.

Not urgent (non regression).

* jk/docs-docbook-monospace-display:
  docs: monospace listings in docbook output

inconsistent.

As the title says.

* hv/submodule-path-unmatch:
  Let submodule command exit with error status if path does not exist
Merge branch 'jc/capabilities' into pu

Some capabilities were asked by fetch-pack even when upload-pack did
not advertise that they are available.  Fix fetch-pack not to do so.

* jc/capabilities:
  fetch-pack: mention server version with verbose output
  parse_feature_request: make it easier to see feature values

mistakes such as saying "y<RETURN>" to sender mail address whose

based on the client address, repository path, etc.

In earlier days, "imitate the style in the neibouring code" was
sufficient to keep the coherent style, but over time some parts of
the codebase have drifted enough to make it ineffective.

* hv/coding-guidelines:
  Documentation/CodingGuidelines: spell out more shell guidelines
Merge branch 'jc/add-delete-default' into pu

"git add dir/" updated modified files and added new files, but does
not notice removed files, which may be "Huh?" to some users.  They
can of course use "git add -A dir/", but why should they?

* jc/add-delete-default:
  git add: notice removal of tracked paths by default
Merge branch 'jc/maint-rev-list-topo-doc' into pu

It was unclear what "--topo-order" was really about in the
documentation. It is not just about "children before parent", but
also about "don't mix lineages".

* jc/maint-rev-list-topo-doc:
  rev-list docs: clarify --topo-order description
