Please add tests to show some command executions (e.g. test output
from "git ls-files", or something).

This seems to allow people to run only a single Git subcommand,
which is probably not what most people want to see. Don't we want
to support something as simple as this?
git for-each-repository sh -c "ls *.c"

Assuming that the non *argv case is for consumption by programs and
scripts (similar to the way "ls-files" output is piped to downstream),
we prefer to (1) support "-z" so that "xargs -0" can read paths with
funny characters, and (2) use quote_c_style() from quote.c when "-z"
is not in effect.

When you are only showing the path to a repository, I do not think
you want setenv() or chdir() at all. Shouldn't these be done inside
handle_repo() function? As you are only dealing with non-bare
repositories (and that is what you print in "listing only" mode
anyway), handle_repo() can borrow path (not path->buf) and append
and strip "/.git" as needed.
Also, while it is a good idea to protect this program from stray
GIT_DIR/GIT_WORK_TREE the user may have in the environment when this
program is started, I think this is not enough, if you allow the
*argv commands to run worktree related operations in each repository
you discover. You would need to chdir() to the top of the working
tree.
The run-command API lets you specify custom environment only for the
child process without affecting yourself by setting .env member of
the child_process structure, so we may want to use that instead of
doing setenv() on ourselves (and letting it inherited by the child).
