renaming a sub-directory with a space in it in git

Suppose you have a git sub-directory with a space in it...

/outer/old name/

It appears you cannot rename the sub-directory with a space in it to a different name which also has a space in it. For example, the following does not work...

git mv -f "outer/old name/" "outer/new name/"

However, after much trial and error, I have found the following which does work...

git mv -f "outer/old name/" "outer/temp-name/"
git commit -m "rename subfolder with space part 1/2"
git mv -f "outer/temp-name/" "outer/new name/"
git commit -m "rename subfolder with space part 2/2"

Hope this proves useful to someone.
