This is kosher POSIX, but I vaguely recall some shells had trouble
with the SP between -C and "$dir" in the past. Let's see if anybody
screams; hopefully I am misremembering or buggy shells died out.
I also am bothered by a vague recollection of some issue (possibly
involving the internal space and lack of quotes around the entire
${...}), but couldn't remember nor find a reference to the specific
details. Perhaps someone reading the patch has a better memory than I.
Probably:

And ea10b60c910e (Work around ash "alternate value" expansion bug,
2009-04-18) as well.

Yikes, you're right. Does anybody know if FreeBSD shell is still
buggy?
git-submodule.sh contains a few offending constructs:
git submodule--helper update-clone ${GIT_QUIET:+--quiet} \
${wt_prefix:+--prefix "$wt_prefix"} \
${prefix:+--recursive-prefix "$prefix"} \
${update:+--update "$update"} \
${reference:+--reference "$reference"} \
${depth:+--depth "$depth"} \
"$@" || echo "#unmatched"
} | {
They were added recently in 48308681b072 (git submodule update: have
a dedicated helper for cloning, 2016-02-29), which is not in any
release yet, perhaps that's why noone complained yet.
