Answer 1

I think it splits on spaces due to IFS (Internal Field Separator). Try defining IFS to newlines:

$ IFS=$'\n' MVAR=($(su - git -C "sftp user@xxx.xxx.xxx.xxx << EOF
pwd
EOF
" ))

I could make your command work on my machine. I used this one to test locally and get the remote pwd:

$ IFS=$'\n' MVAR=($(sftp -b <(echo pwd) localhost))
$ echo ${abc[1]}
sftp> pwd
$ echo ${abc[2]}
