Either end of revision range operator can be omitted to default to HEAD,
as in "origin.." (what did I do since I forked) or "..origin" (what did
they do since I forked). But the current parser interprets ".." as an
empty range "HEAD..HEAD", and worse yet, because ".." does exist on the
filesystem, we get this annoying output:
$ cd Documentation/howto
$ git log .. ;# give me recent commits that touch Documentation/ area.
fatal: ambiguous argument '..': both revision and filename
Use '--' to separate filenames from revisions
Surely we could say "git log ../" or even "git log -- .." to disambiguate,
but we shouldn't have to.

It was a bit hard to learn how <rev>^@, <rev>^! and various other
forms of range specifiers are used, because they were discussed
mostly in the prose part of the documentation, unlike various forms
of extended SHA-1 expressions that are listed in an enumerated list.
Also add a few more examples showing use of <rev>, <rev>..<rev> and
<rev>^! forms, stolen from a patch by Max Horn.

Formerly, the documentation for <refname> would occasionally say
<name> instead of <refname>. Now it uniformly uses <refname>.

We explained <rev>~<n> as <n>th generation grand-parent, but a reader got
confused by the "grand-" part when <n> is 1.
Reword it with "ancestor"; with the "generation" and "following only the
first parents" around there, what we try to describe should be clear
enough now.

Currently, the reader has to parse a textual description in order to
find a specific syntax in the list.
Restructure as a labelled list with systematic labels as well as
concrete examples as a visual guide.

Our use of quotes is inconsistent everywhere and within some files.
Before reworking the structure of revisions.txt, make the quotes
consistent:
`git command`
'some snippet or term'
The former gets typeset as code, the latter with some form of emphasis.
the man backend uses two types of emphasis.

When a cherry-pick conflicts git advises:
$ git commit -c <original commit id>
to preserve the original commit message and authorship. Instead, let's
record the original commit id in CHERRY_PICK_HEAD and advise:
$ git commit -c CHERRY_PICK_HEAD
A later patch teaches git to handle the '-c CHERRY_PICK_HEAD' part.
Note that we record CHERRY_PICK_HEAD even in the case where there
are no conflicts so that we may use it to communicate authorship to
commit; this will then allow us to remove set_author_ident_env from
revert.c. However, we do not record CHERRY_PICK_HEAD when --no-commit
is used, as presumably the user intends to further edit the commit
and possibly even cherry-pick additional commits on top.

* nd/oneline-sha1-name-from-specific-ref:
get_sha1: handle special case $commit^{/}
get_sha1: support $commit^{/regex} syntax
get_sha1_oneline: make callers prepare the commit list to traverse
get_sha1_oneline: fix lifespan rule of temp_commit_buffer variable
This works like ":/regex" syntax that finds a recently created commit
starting from all refs, but limits the discovery to those reachable from
the named commit.

Currently :path and ref:path can be used to refer to a specific object
in index or ref respectively. "path" component is absolute path. This
patch allows "path" to be written as "./path" or "../path", which is
relative to user's original cwd.
This does not work in commands for which startup_info is NULL
(i.e. non-builtin ones, it seems none of them needs this anyway).

Currently, the documentation for revisions and ranges sits in the
git-rev-parse man page, i.e. a plumbing man page, along with the
documentation of all rev-parse modes.
Split off the revisions and ranges section into an included file to
prepare for restructuring.
