The "${var+if_set_use_this}" interpolates if $var is set (as opposed to
"unset"); this will cause it to have "--strategy= " in strategy_args
when $do_merge is set. If you ran t3421, you would have noticed
breakage.
You should use ${var:+if_set_to_nonempty_use_this} here.
stragety_opts is designed to be a valid shell scriptlet that can be
inserted as a part of eval'ed string. git-rebase.sh does this:
-X)
shift
strategy_opts="$strategy_opts $(git rev-parse --sq-quote "--$1")"
do_merge=t
so that git-rebase--merge.sh can use it like so:
eval 'git-merge-$strategy' $strategy_opts '"$cmt^" -- "$hd" "$cmt"'
without having to worry about quoting issues when future strategy
options have letters that need quoting, e.g.
$ git rebase -X foo="bar ' baz"
git rev-parse --sq-quote turns it into '--foo=bar '\'' baz' and then
in the eval'ed string, it becomes a single argument given to the
git-merge-$strategy command, even though it may have spaces and
single quotes and other characters that may be tricky to quote
manually without mistakes.
So munging it manually with sloppy "sed" script is simply wrong.
