- From my man page:
-, -l, --login
make the shell a login shell, clears all envvars except for
TERM, initializes HOME, SHELL, USER, LOGNAME and PATH
The login shell is a bit problematic, but initializing USER, LOGNAME,
and PATH (the Tomcat user has a restricted path) is useful.
I don't see the restriction on su for '-' that your man page mentions.
We're running CentOS 6.5 / 6.6 in production, and I run Fedora 20 on
my laptop. I'm working on vetting a CentOS 7 (systemd) script, but as
usual other things keep impacting my time.

That's why the following line is in quotes:
"${CONFIG_OPTS} ${CAT_PID} ${TOMCAT_INSTANCE} start"
${CONFIG_OPTS} does contain spaces, and the resulting command
obviously contains spaces.
While the shell script is long and ugly, there are only a few places
where spaces crop up. I seem to have them all covered.

I'm looking at Chef to manage a lot of this in the future, depending
on how much Ruby programming is needed. I can then place everything in
version control, which makes me a much happier camper.
. . . just my two cents
