Missing space between non required options in help synopsis

[joanneshen]

Hi,
After upgrading to spring-shell v4, when running help of a command, a space is missing between different name/value pair of options. See example as follows.

help run
NAME
run - Runs a job, scheduling it to run immediately.

SYNOPSIS
run --d RestFolder--applications String[]--app String[]--properties String[]--p String[] --help

While SYNOPSIS is supposed to be like this:
run --d RestFolder --applications String[] --app String[] --properties String[] --p String[] --help
