The insertion range for completion items was not right. The range's
end was 1 before the start. Fix by taking into account the length of
the prefix when generating the range start and end.
Now instead of a "prefix", we track the completion's
"surrounding". This is basically the start and end of the abutting
identifier along with the cursor position. When we insert the
completion text, we overwrite the entire identifier, not just the
prefix. This fixes postfix completion like completing "foo.<>Bar" to
"foo.BarBaz".

At least inside this one package.
It's because golang.org/x/tools/cmd/godoc no longer has CLI support
as of golang/go#25443, it is now only a web server. Luckily, browsers
that display HTML pages are not constrained to the fixed width of
punched cards. On the contrary, they seem to embrace a wide variety of
arbitrary page widths, ranging from narrow to wide. This is in part due
to the proliferation of internet access on device form factors such as
the mobile phone, tablet, laptop, and desktop.
So the punchCardWidth constant is now unused and can be removed. This
is a followup to CL 141397 that removed most of the CLI support code,
including the function comment_textFunc, which was its only user. Same
goes for containsOnlySpace.

Fix the following issues:
- We were trying to complete struct literal field names for

names in this case if the expression is an *ast.Ident.
- We weren't including lexical completions in cases where you might be
completing a field name or a variable name (e.g. "Foo{A<>}").
I refactored composite literal logic to live mostly in one place. Now
enclosingCompositeLiteral computes all the bits of information related
to composite literals. The expected type, completion, and snippet code
make use of those precalculated facts instead of redoing the work.

and then also
{x==2, x==3, x==4}
{x==3, x==4}
Since the comparison is itself linear in the size of the set, this was overall
taking time quadratic in the length of the || or && sequence.
Worse, if it found duplicates, they'd be reported a quadratic number of times.
This CL cuts the time and output to linear by avoiding already-checked
