[Samba] SWAT drops quoted text in options

Having a little trouble with SWAT in Samba 3.0.3.

When an option in smb.conf contains quotes, for example:

	add group script = /path/to/addgroupscript "%g"

SWAT will, upon parsing smb.conf, display

	add group script = /path/to/addgroupscript

and committing it causes the quoted portion to be dropped in smb.conf.

Note that anything in double quotes (or, rather, after the first double
quote) is dropped. Using single quotes seems to be OK.

In some instances, placing items in quotes is necessary to avoid
breaking things when an item contains spaces.

This problem appears to be with SWAT and not Samba itself. Perhaps the
documentation should say a little more clearly that single quotes are
preferable to double quotes when using SWAT?

I found this in the archives, is it something that needs to be
revisited by the Samba team?:

> Hello,

> smb.conf will result in @ in swat.
