4e13c7cbc1 SC2164: show two possible variants for circumenting the warning 
always calling 'exit' is not good in e.g. functions.
the basic idea is at least that the returncode of
cd *is* evaluated somehow and not ignored.

0897ab7092 Add handling for special characters in parameter substitutions. 
Fixes koalaman/shellcheck#562. Special characters inside braces are
parsed into T_ParamSubSpecialChar instead of T_Literal so that they are
not flagged in the function checkInexplicablyUnquoted when sandwiched
between double quotes.
