Many uses of Index/IndexByte/IndexRune/Split/SplitN
can be written more clearly using the new Cut functions.
Do that. Also rewrite to other functions if that's clearer.
For #46336.

p.literal's doc comment said it returned a value but it doesn't.
While we're here, p.newLiteral is only called from p.literal,
so simplify the code by merging the two.

This reverts commit 08f19bbde1b01227fdc2fa2d326e4029bb74dd96.
Reason for revert:
The changed transformation takes effect on a larger set
of code snippets than expected.
For example, this:
func foo() {
// Comment
bar()
}
becomes:
func foo() {
// Comment
bar()
}
This is an unintended consequence.

To improve readability when exported fields are removed,
forbid the printer from emitting an empty line before the first comment
in a const, var, or type block.
Also, when printing the "Has filtered or unexported fields." message,
add an empty line before it to separate the message from the struct
or interfact contents.
Before the change:
<<<
type NamedArg struct {
// Name is the name of the parameter placeholder.
//
// If empty, the ordinal position in the argument list will be
// used.
//
// Name must omit any symbol prefix.
Name string
// Value is the value of the parameter.
// It may be assigned the same value types as the query
// arguments.
Value interface{}
// contains filtered or unexported fields
}
>>>
After the change:
<<<
type NamedArg struct {
// Name is the name of the parameter placeholder.
//
// If empty, the ordinal position in the argument list will be
// used.
//
// Name must omit any symbol prefix.
Name string
// Value is the value of the parameter.
// It may be assigned the same value types as the query
// arguments.
Value interface{}

The tree's pretty inconsistent about single space vs double space
after a period in documentation. Make it consistently a single space,
per earlier decisions. This means contributors won't be confused by
misleading precedence.

This is a subset of https://golang.org/cl/20022 with only the copyright
header lines, so the next CL will be smaller and more reviewable.
Go policy has been single space after periods in comments for some time.
The copyright header template at:
https://golang.org/doc/contribute.html#copyright
also uses a single space.
Make them all consistent.

In the past, `a.*?c|a.*?b` was factored to `a.*?[bc]`. Thus, given
"abc" as its input string, the automaton would consume "ab" and
then stop (when unanchored) whereas it should consume all of "abc"
as per leftmost semantics.
Fixes#13812.

It's not a group: must handle the inside as a sequence of literal chars,
not a single literal string.
That is, \Qab\E+ is the same as ab+, not (ab)+.
