Freddy Vulto eb860b7b9f Added helper function __expand_tilde_by_ref()
Expands only tilde (~), if first char, in variable.
This function displays bash's capabilities of passing a variable by
reference (variable indirection) which allows us to avoid using a
subshell.  As far as I can see it works surprisingly well?

To run the automated test:

    ./runUnit __expand_tilde_by_ref.exp

Also fixed some testsuite issues regarding list splitting.
