Well, if you were trying to be portable to multiple shells, then it
would matter.  But as this script is explicitly being run under
/bin/bash, and as bash already has support for declaration utilities
where local is one such utility, your script as written is safe without
"" in the arguments to local.  So I'm fine whether you choose to change
it in a respin or to leave it as written in this version.
