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. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
