pgbench - add option to show actual builtin script code

Hello devs,

The minor attached patch $SUBJECT, so that it can be inspected easily, 
instead of having to look at the source code or whatever.

   sh> pgbench --list select-only
   -- select-only: <builtin: select only>
   \set aid random(1, 100000 * :scale)
   SELECT abalance FROM pgbench_accounts WHERE aid = :aid;

The builtin list output is also slightly improved:

   sh> pgbench -b list
   Available builtin scripts:
         tpcb-like: <builtin: TPC-B (sort of)>
     simple-update: <builtin: simple update>
       select-only: <builtin: select only>

The following review has been posted through the commitfest application:
make installcheck-world:  tested, passed
Implements feature:       tested, passed
Spec compliant:           tested, passed
Documentation:            tested, passed

Patch looks good to me, and work fine on my machine. One minor observation is option 'list' mostly used to list the
elementslike "pgbench -b list" shows the available builtin scripts. Therefore we should use a word which seems to be
morerelevant like --show-script. 

The new status of this patch is: Waiting on Author

Thanks for the review.

Here is a version with "--show-script". I also thought about "--listing", 
maybe.

Why aren't we instead putting the exact scripts in the documentation?
Having to call pgbench with a special flag to get the script text seems
a bit odd.


cheers

A typical use case I had is to create a new script by modifying an 
existing one for testing or debug. I prefer "command > file.sql ; vi 
file.sql" to hazardous copy-pasting stuff from html pages.

I do not think that it is worth replicating all scripts inside the doc, 
they are not that interesting, especially if more are added. Currently, 
out of the 3 scripts, only one is in the doc, and nobody complained:-)

Now, they could be added to the documentation, but I'd like the option 
anyway.
