Denys Vlasenko 88ac97d02d ash: [EXPAND] Do not split quoted VSLENGTH and VSTRIM
Upstream patch:

    Date: Wed, 8 Oct 2014 15:42:08 +0800
    [EXPAND] Do not split quoted VSLENGTH and VSTRIM

    Currently VSLENGTH and VSTRIM* are field-split even within quotes.
    This is obviously wrong.  This patch fixes that.
