One edge-case that isn't currently checked in the tests is the beginning
of the path matching the work tree, despite the target not actually
being the work tree, for example:
path = /dir/repoa
work_tree = /dir/repo
should fail since the path is outside the repo. However, if /dir/repoa
is in fact a symlink that points to /dir/repo, it should instead
succeed.
Add two tests covering these cases, since they might be potential
regression points.

The current behaviour of prefix_path is to return an empty string if
prefixing and absolute path that only contains exactly the work tree.
This behaviour is a potential regression point.

When symlinks in the working tree are manipulated using the absolute
path, git dereferences them, and tries to manipulate the link target
instead.
This applies to most high-level commands but prefix_path is the common
denominator for all of them.
Add a known-breakage tests using the prefix_path function, which
currently uses real_path, causing the dereference.

When symlinks in the working tree are manipulated using the absolute
path, git dereferences them, and tries to manipulate the link target
instead.
This causes most high-level functions to misbehave when acting on
symlinks given via absolute paths. For example
$ git add /dir/repo/symlink
attempts to add the target of the symlink rather than the symlink
itself, which is usually not what the user intends to do.
This is a regression introduced by 18e051a:
setup: translate symlinks in filename when using absolute paths
(which did not take symlinks inside the work tree into consideration).
Add a known-breakage test using the ls-files function, checking both if
the symlink leads to a target in the same directory, and a target in the
above directory.

This goes far back to e84fb2f (branch --contains: default to HEAD -
2008-07-08) where the same parsing code is shared with
builtin/tag.c. git-branch.txt correctly states that <commit> for
--contains is optional while git-tag.txt does not. Correct it.

Remove a check on the number of arguments for --onto and -x options.
It is not possible for $# to be <= 2 at this point :
- if --onto or -x has an argument, git rev-parse --parseopt will
provide something like this :
set -- --onto 'x' --
when parsing the "--onto" option, $# will be 3 or more if there are
other options.
- if --onto or -x doesn't have an argument, git rev-parse --parseopt
will exit with an error and display usage information.

When we see config like:
[include]
path
the expand_user_path helper notices that the config value is
empty, but we then dereference NULL while printing the error
message (glibc will helpfully print "(null)" for us here,
but we cannot rely on that).
$ git -c include.path rev-parse
error: Could not expand include path '(null)'
fatal: unable to parse command-line config
Instead of tweaking our message, let's actually use
config_error_nonbool to match other config variables that
expect a value:
$ git -c include.path rev-parse
error: Missing value for 'include.path'
fatal: unable to parse command-line config

We explicitly check for and handle the case that the
incoming "path" variable is NULL, but before doing so we
call strchrnul on it, leading to a potential segfault.
We can fix this simply by moving the strchrnul call down; as
a bonus, we can tighten the scope on the associated
variable.
