Subject: [PATCH] completion: fix multiple command removals

Commit 6532f3740b ("completion: allow to customize the completable command list", 2018-05-20) tried to allow multiple space-separated entries in completion.commands. To do this, it copies each parsed token into a strbuf so that the result is NUL-terminated.

However, for tokens starting with "-", it accidentally passes the original non-terminated string, meaning that only the final one worked. Switch to using the strbuf.
