worktree.c contains functions to work with and get information from
worktrees. This introduction moves functions related to worktrees
from branch.c into worktree.c

Which "if" does this "else if" pair with? I think you would want to
clarify not with indentation but with a brace here.
if (!strbuf_readlink(...)) {
/* HEAD is a symlink */
if (!starts_with(...) || check_refname_format(...))
return -1; /* malformed */
} else if (strbuf_read_file(...) >= 0) {
/* textual symref */
...
Alternatively, you could do it this way.
if (!strbuf_readlink(...) &&
(!starts_with(...) || check_refname_format(...)))
return -1;
else if (strbuf_read_file(...) >= 0) {
...
I do not know which one is more readable, though. Probably former,
even though it is a bit more verbose, is easier to follow.

The worktree structure provided for an individual worktree includes the
absolute path of the worktree. The fuction to get the worktree details
is a refactor of the find main/linked symref functions.

In addition to the absolute path in the worktree struct, add the location
of the git dir, the head ref (if not detached), the head revision sha1,
whether or not head is detached, and whether or not the worktree is a
bare repo.

'git worktree list' iterates through the worktree list, and outputs
details of the worktree including the path to the worktree, the currently
checked out revision and branch, and if the work tree is bare. There is
also porcelain format option available.

+LIST OUTPUT FORMAT
+------------------
+The worktree list command has two output formats. The default format shows the
+details on a single line with columns. For example:
+
+------------
+S git worktree list
+/path/to/bare-source (bare)
+/path/to/linked-worktree abcd1234 [master]

+
+Porcelain Format
+~~~~~~~~~~~~~~~~
+The porcelain format has a line per attribute. Attributes are listed with a
+label and value separated by a single space. Boolean attributes (like 'bare'
+and 'detached') are listed as a label only, and are only present if and only
+if the value is true. An empty line indicates the end of a worktree. For
+example:
+
+------------
+S git worktree list --porcelain

decl-after-stmt.
If I were doing this, I'd probably do something like the attached
using a small helper function to make the primary logic easier to
see.
The first hunk below is unrelated but was to fix an obvious style
breakage I happened to have noticed nearby.
Thanks.
