The argument to --diff-algorithm is mandatory, so there is no reason to
require the argument to be stuck to the option with '='. Change this
for consistency with other Git commands.
Note that this doesi not change the handling of diff-algorithm in
merge-recursive.c since the primary interface to that is via the -X
option to 'git merge' where the unstuck form does not make sense.
