	This token is a potential argument/command that will be forwarded to argv.
constexpr int	NO_WORD_SPLIT = 1 << 4
	This token is not eligible for word splitting.

Note

Wildcard expansion is disabled for double quoted strings by default. To enable it, define ENABLE_DOUBLE_QUOTE_WILDCARD_SUBSTITUTION in CMakeLists.txt.

Glob expansion is not performed for COMMAND tokens by default due to requirement We ignore masks in the program name. However, this behavior is unnatural.
