pub fn pattern_has_glob_metacharacters(
    pattern: &str,
    enable_extended_globbing: bool,
) -> bool

Uses the same PEG grammar rules that pattern_to_regex_str uses, keeping a single source of truth for what constitutes a glob metacharacter.

Arguments

• pattern - The shell pattern to check.
• enable_extended_globbing - Whether to enable extended globbing (extglob).
