https://bugzilla.redhat.com/show_bug.cgi?id=609044 complained
that 'virsh help pool-create-as' didn't document the shortcut
that you can do 'virsh pool-create-as $name $type --target $target'
rather than having to supply the four optional source- arguments
in order to fill out the necessary positional arguments.
This one-liner changes the help output to hopefully make this more obvious:
NAME
pool-create-as - create a pool from a set of args
SYNOPSIS
pool-create-as <name> [--print-xml] <type> [<source-host>]
[<source-path>] [<source-dev>] [<source-name>] [<target>]
[--source-format <string>]
DESCRIPTION
Create a pool.
OPTIONS
[--name] <string> name of the pool
--print-xml print XML document, but don't define/create
[--type] <string> type of the pool
[--source-host] <string> source-host for underlying storage
[--source-path] <string> source path for underlying storage
[--source-dev] <string> source device for underlying storage
[--source-name] <string> source name for underlying storage
[--target] <string> target for underlying storage
--source-format <string> format for underlying storage
* tools/virsh.c (vshCmddefHelp): Make it more obvious that data
arguments may, but not must, be specified by option leaders.

Wow - the commit message is 30 times bigger than the commit itself!
If additionally wanted, I could make the help output wrap if the
left column is long, so that the right column lines up, looking more like:
OPTIONS
[--name] <string> name of the pool
--print-xml print XML document, but don't define/create
[--type] <string> type of the pool
[--source-host] <string>
source-host for underlying storage
[--source-path] <string>
source path for underlying storage
[--source-dev] <string>
source device for underlying storage
[--source-name] <string>
source name for underlying storage
[--target] <string> target for underlying storage
--source-format <string>
format for underlying storage
