This was indeed a bit surprising, but after re-reading the commit message,
it became clear what this is all about.
But I wonder...

As we no longer accept any command-line arguments, (and as the `create`
command *explicitly* allows messages starting with a dash), it would
probably make more sense to test `argc` directly:
if (!argc)
usage_with_options(git_stash_create_usage, options);

... this adds an extra space at the end, right? I guess this should read
instead:
for (i = 0; i < argc; i++) {
if (i > 0)
strbuf_addch(&stash_msg_buf, ' ');
strbuf_addstr(&stash_msg_buf, argv[i]);
}

As we no longer have any way to set `stash_msg` via an option, this
variable should go away.
And rather than detaching the strbuf here, it would be better to release
it after the call to `do_create_stash()`. (And the `to_free` variable is
no longer necessary, either.)

Is this `if (argc)` guard necessary?

I *think* this is missing the `n`.
