- Define a general non-"contained" "shBracketExpr" group,
and replace with it the "contained" bracket variant of
"shOperator", adjusting the patterns for the competing
conditional commands "[" and "[[".
- Accommodate some unbalanced brackets (e.g. "[!][!]").
- Make the leading "!" (or "^") stand out in NON-matching
bracket expressions.
- Support literal newlines in parametric patterns (along
with pathname globbings and "case" patterns).
- Also match bracket expressions in:
* parametric patterns (e.g. "${1#[ab]_}");
* pathname globbings (e.g. "[ab]*.txt");
* arguments for the "[[", "echo", and "print" commands.
- Recognise collating symbols (e.g. "[.a.]") and equivalence
classes (e.g. "[=a=]").
- Recognise end patterns for a pattern substitution form of
parameter expansion and match bracket expressions in such
patterns (e.g. "${1/%[.!]/;}").
