5. An atom can be one of a long list of items. Many atoms match one character
in the text. It is often an ordinary character or a character class.
Braces can be used to make a pattern into an atom. The "\z(\)" construct
is only for syntax highlighting.
Parentheses can be used to make a pattern into an atom. The "\z(\)"

The brackets in character class expressions are additional to the
brackets delimiting a collection. For example, the following is a
plausible pattern for a UNIX filename: "[-./[:alnum:]_~]\+" That is,
a list of at least one character, each of which is either '-', '.',
'/', alphabetic, numeric, '_' or '~'.

regexp engine. See |two-engines|. In the future these items may
