The previous function regex required explicit matching of function
bodies using `{`, `(`, `((`, or `[[`, which caused several issues:
- It failed to capture valid functions where `{` was on the next line
due to line continuation (`\`).
- It did not recognize functions with single command body, such as
`x () echo hello`.
Replacing the function body matching logic with `.*$`, ensures
that everything on the function definition line is captured.
Additionally, the word regex is refined to better recognize shell
syntax, including additional parameter expansion operators and
command-line options.
