This solves several problems that arise from the special treatment of
"=" in Bash.
The fix was required as some log drivers have options in a key=value
form. It also addresses the --option=value and the negated boolean syntax
(--boolean=false).
Note that this is not a general fix for these problems, it is limited to
the __docker_pos_first_nonflag function.
