#@642 Alist of sexp form regexp constituents.
Each element of the alist has the form (SYMBOL . DEFN).
SYMBOL is a valid constituent of sexp regular expressions.
If DEFN is a string, SYMBOL is translated into DEFN.
If DEFN is a symbol, use the definition of DEFN, recursively.
Otherwise, DEFN must be a list (FUNCTION MIN-ARGS MAX-ARGS PREDICATE).
FUNCTION is used to produce code for SYMBOL.  MIN-ARGS and MAX-ARGS
are the minimum and maximum number of arguments the function-form
sexp constituent SYMBOL may have in sexp regular expressions.
MAX-ARGS nil means no limit.  PREDICATE, if specified, means that
all arguments must satisfy PREDICATE.

#@988 Return non-nil if regexp string R is atomic.
An atomic regexp R is one such that a suffix operator
appended to R will apply to all of R.  For example, "a"
"[abc]" and "\(ab\|ab*c\)" are atomic and "ab",
"[ab]c", and "ab\|ab*c" are not atomic.

This function may return false negatives, but it will not
return false positives.  It is nevertheless useful in
situations where an efficiency shortcut can be taken only if a
regexp is atomic.  The function can be improved to detect
more cases of atomic regexps.  Presently, this function
detects the following categories of atomic regexp;

  a group or shy group:  \(...\)
  a character class:     [...]
  a single character:    a

On the other hand, false negatives will be returned for
regexps that are atomic but end in operators, such as
"a+".  I think these are rare.  Probably such cases could
be detected without much effort.  A guarantee of no false
negatives would require a theoretic specification of the set
of all atomic regexps.

REGEXPS is a non-empty sequence of forms of the sort listed below.

Note that `rx' is a Lisp macro; when used in a Lisp program being
 compiled, the translation is performed by the compiler.
See `rx-to-string' for how to do such a translation at run-time.

The following are valid subforms of regular expressions in sexp
notation.

STRING
     matches string STRING literally.

     Ranges of characters can be specified as `A-Z' in strings.

     SET may also be the name of a character class: `digit',
     `control', `hex-digit', `blank', `graph', `print', `alnum',
     `alpha', `ascii', `nonascii', `lower', `punct', `space', `upper',
     `word', or one of their synonyms.

`(not (any SET ...))'

`line-start', `bol'

     in the text being matched

`line-end', `eol'

`(not (category CATEGORY))'
     matches a character that doesn't have category CATEGORY.

`(and SEXP1 SEXP2 ...)'
`(: SEXP1 SEXP2 ...)'
`(seq SEXP1 SEXP2 ...)'
`(sequence SEXP1 SEXP2 ...)'
     matches what SEXP1 matches, followed by what SEXP2 matches, etc.

`(submatch SEXP1 SEXP2 ...)'
`(group SEXP1 SEXP2 ...)'
     like `and', but makes the match accessible with `match-end',
     `match-beginning', and `match-string'.

`(submatch-n N SEXP1 SEXP2 ...)'
`(group-n N SEXP1 SEXP2 ...)'
     like `group', but make it an explicitly-numbered group with
     group number N.

`(or SEXP1 SEXP2 ...)'
`(| SEXP1 SEXP2 ...)'
     matches anything that matches SEXP1 or SEXP2, etc.  If all
     args are strings, use `regexp-opt' to optimize the resulting
     regular expression.

`(minimal-match SEXP)'
     produce a non-greedy regexp for SEXP.  Normally, regexps matching
     zero or more occurrences of something are "greedy" in that they
     match as much as they can, as long as the overall regexp can
     still match.  A non-greedy regexp matches as little as possible.

`(maximal-match SEXP)'
     produce a greedy regexp for SEXP.  This is the default.

Below, `SEXP ...' represents a sequence of regexp forms, treated as if
enclosed in `(and ...)'.

`(zero-or-more SEXP ...)'
`(0+ SEXP ...)'
     matches zero or more occurrences of what SEXP ... matches.

`(* SEXP ...)'
     like `zero-or-more', but always produces a greedy regexp, independent
     of `rx-greedy-flag'.

`(*? SEXP ...)'
     like `zero-or-more', but always produces a non-greedy regexp,
     independent of `rx-greedy-flag'.

`(one-or-more SEXP ...)'
`(1+ SEXP ...)'
     matches one or more occurrences of SEXP ...

`(+ SEXP ...)'
     like `one-or-more', but always produces a greedy regexp.

`(+? SEXP ...)'
     like `one-or-more', but always produces a non-greedy regexp.

`(zero-or-one SEXP ...)'
`(optional SEXP ...)'
`(opt SEXP ...)'
     matches zero or one occurrences of A.

`(? SEXP ...)'
     like `zero-or-one', but always produces a greedy regexp.

`(?? SEXP ...)'
     like `zero-or-one', but always produces a non-greedy regexp.

`(repeat N SEXP)'
`(= N SEXP ...)'
     matches N occurrences.

`(>= N SEXP ...)'
     matches N or more occurrences.

`(repeat N M SEXP)'
`(** N M SEXP ...)'
     matches N to M occurrences.

`(backref N)'
     matches what was matched previously by submatch N.

`(eval FORM)'
     evaluate FORM and insert result.  If result is a string,
     `regexp-quote' it.

`(regexp REGEXP)'
     include REGEXP in string notation in the result.
