~60 global variables use by only one function in bash source

[Peng Yu]

Hi,

I see these global or static variables (1st column) used only by one
function (2nd column). Some are from bash, some are from the libraries
that bash depends.

It seems to be problematic to declare variables global/static but only
to use them in one function. Should these variables be made local?

Thanks.
