d22e0aa4a7 Simplify process 
Note to self: This is a lot like foldr or traverse, and would be trivial to
implement as such if it didn't need to peek ahead when takesArg is true. I
wonder if there's a clean way to implement it in terms of one of them anyway.

67e091674e Remove unnecessary maybeToList 
The functions we use here are polymorphic enough to work in the [] monad,
so there's no point to use them in the Maybe monad and then convert.

fdd02c94c0 Issue 1759 mapfile and process substition 
https://github.com/koalaman/shellcheck/issues/1759

When a simple process substition is used, this tripped up
the getMapfileArray function by making the last argument
not a variable

0e0de94045 Fix issue #1724 
(bash: missing support for 'builtin' keyword)
Now shellcheck looks for the arguments to 'builtin' to determine
read/written variables. A change in the parser makes sure that
assignments are parsed correctly in commands that start with 'builtin'.
