461be74976 Realign virtual tabs when applying fix
Fix an off-by-one error, in the case that is commented `should never happen`.
It happens when the end of a range is the at the end of a line.
In that case we should update the real column count (probably just by +1)
instead of returning it.

I modified makeNonVirtual to use a helper, realign, that works on
Ranged. That way we can share the code to realign a PositionedComment
and also a Replacement.

Fixes #1420

95a8cf93c9 Add check for ambiguous nullary test
Given an input like `if [[ $(a) ]]; then ...`, this is a implicit `-n` test,
so it works like `if [[ -n $(a) ]]; then ...`. Users might confuse this for
a check for the exit code of the command a, which should be tested with:

    if a; then
        ...

We warn the user to be more explicity and specifity the `-n`.

Fixes #1416

5f1c969546 getParentTree: avoid pattern matching in do notation
Pattern matching in "do" requires a MonadFail context, which we don't have in
pure code. Instead, we'll use "case-of" to bind the part of the state that
we're interested in.

07f04e13ce Understand array variable declaration in read (fixes #679 fixes #1272)
It used to only treat all trailing variables in read as varaible
declarings, but an array variable can be declared in other positions:

    read -a foo -r

foo is a declared variable, and multiple such variables can be declared.
