get_remote_merge_branch with zero or one arguments returns the
upstream branch. But a detached HEAD does no have an upstream branch,
as it is not tracking anything. Handle this case testing the exit code
of "git symbolic-ref -q HEAD".

Use the {asterisk} entity to avoid mistreating the asterisks
in "(e.g., refs/heads/*:refs/remotes/origin/*)" as delimiters
for bold text.

From a quick search with 'git grep -e "\*.*\*"', this seems to
be the last example of this particular formatting problem.

The manual pages of cherry-pick and revert had examples with two revisions
on the same line in the examples section, that looked like this:

    git cherry-pick master~4 master~2::

Unfortunately, this is taken as a mark-up to make the part between two
tildes, "4 master", subscript.  Use {tilde} to make it explicit that we
do want ~ characters in these places (backslash does not help).

The "[add] ignore-errors" tweakable introduced by v1.5.6-rc0~30^2 (Add
a config option to ignore errors for git-add, 2008-05-12) does not
follow the usual convention for naming values in the git configuration
file.

What convention?  Glad you asked.

	The section name indicates the affected subsystem.

	The subsection name, if any, indicates which of
	an unbound set of things to set the value for.

	The variable name describes the effect of tweaking
	this knob.

	The section and variable names can be broken into
	words using bumpyCaps in documentation as a hint to
	the reader.  These word breaks are not significant
	at the level of code, since the section and variable
	names are not case sensitive.

The name "add.ignore-errors" includes a dash, meaning a naive
configuration file like

	[add]
		ignoreErrors

does not have any effect.  Avoid such confusion by renaming to the
more consistent add.ignoreErrors, but keep the old version for
backwards compatibility.

Bad graft data is noticed in several places in read_graft_line(), and in
each case we go back to the first site of detection.  It in general is a
better style to have an exception handling out of line from the main
codepath and make error codepath jump forward.

The bash prompt would display a commit's object name when having checked
out a lightweight tag.  Provide `--tags` to `git describe` in the completion
script, so it will display lightweight tag names, as it already does for
annotated tags.
