What would you rather use?

[ "$__git_merge_strategies" ] &&
__git_merge_strategies=$(__git_list_merge_strategies)

That's 90 characters long. Although much better without the 2>/dev/null.

if [ "$__git_merge_strategies" ]; then
  __git_merge_strategies=$(__git_list_merge_strategies)
fi

That's even more lines =/
