- Drop the remaining undefined "shFunctionStart" references
(gone in v7.2b.000, c236c16d0).
- Revise nestable contexts where function definitions are
supported:
* Stop looking for function definitions in arithmetic
expressions.
* Recognise function definitions enclosing other function
definitions.
- In addition to grouping commands "{}" and "()", also match
other compound commands (e.g. "if"; see "shFunctionCmd*")
whenever these commands are supported as complete function
bodies.
- Balance body delimiters "(" and ")" for "shFunctionFour"
in Bash; match such function bodies whenever the use of
the function parameter list "()" token is optional, i.e.
when the "function" reserved word is present.
- Enable the use of "shFunctionFour" definitions.
- Do not claim optional leading whitespace characters before
a matched function definition.
- Prefer patterns with ASCII atoms (e.g. "\h") to equivalent
collections (e.g. "[A-Za-z_]") for speed.
- Accommodate word-boundary assertions in function name
patterns to names that may start and/or end with supported
non-word characters, e.g. "@test:".
- Match more valid function names in Bash: non-ASCII names,
non-word names.
- Allow for function names with "do", "done", etc. prefixes;
confine these name checks to "shDoError" and "shIfError".
