If ${GIT_DIR}/.nextmsg exists, the text will be copied into the .editmsg file
together with a sentinel line prior to invoking the editor.
After editing, the edited text (but not the status lines) are saved
back to the ${GIT_DIR}/.nextmsg file.
If the sentinel line still exists in .editmsg after editing, the
file is truncated, thereby causing the commit to abort (per previous
behaviour).
The ${GIT_DIR}/.nextmsg file is deleted if, and only if,
the commit was successful.
The behaviour of git-commit-script is unchanged with respect to the
previous versions if ${GIT_DIR}/.nextmsg does not exist.
