Add the "[--]" for those cases where the *.txt and -h were
inconsistent, or where we incorrectly stated in one but not the other
that the "--" was mandatory.
In the case of "rev-list" both sides were wrong, as we we don't
require one or more paths if "--" is used, e.g. this is OK:
git rev-list HEAD --
That part of this change is not a "doc txt & -h consistency" change,
as we're changing both versions, doing so here makes both sides
consistent.

Fix various inconsistencies between command SYNOPSIS and the
corresponding -h output where our translatable labels didn't match
up.
In some cases we need to adjust the prose that follows the SYNOPSIS
accordingly, as it refers back to the changed label.

cmd_for_each_repo() copies argv into args (a strvec), which is later
passed into run_command_on_repo(), which in turn copies that strvec onto
the end of child.args. The initial copy is unnecessary (we never modify
args). We therefore choose to just pass argv directly into
run_command_on_repo(), which lets us avoid the copy and fixes the leak.

See also discussion about the original implementation below - this code
appears to have evolved from a callback explaining the double-strvec-copy
pattern, but there's no strong reason to keep that now:

'git for-each-repo --config=X' should return success without calling any
subcommands when the config key 'X' has no value. The current
implementation instead segfaults.
A user could run into this issue if they used 'git maintenance start' to
initialize their cron schedule using 'git for-each-repo
--config=maintenance.repo ...' but then using 'git maintenance
unregister' to remove the config option. (Note: 'git maintenance stop'
would remove the config _and_ remove the cron schedule.)
Add a simple test to ensure this works. Use 'git help --no-such-option'
as the potential subcommand to ensure that we will hit a failure if the
subcommand is ever run.

It can be helpful to store a list of repositories in global or system
config and then iterate Git commands on that list. Create a new builtin
that makes this process simple for experts. We will use this builtin to
run scheduled maintenance on all configured repositories in a future
change.
The test is very simple, but does highlight that the "--" argument is
optional.
