Fix use of pwd in renderSettings proc

renderSettings was using the 'pwd' binary instead of the 'pwd' Tcl call,
which cause issue when PATH is empty. Code has been adapted to reuse the
value of the 'cwd' global variable or set its value by calling the 'pwd'
Tcl function.

Set a ref count of 1 for path without ref count

When a path is used in a variable but does not own a reference count
assume this count is 1 rather than 999999999 to be able to unload it
afterward which would not be possible if this path is referred 999999999
times.
