ash: [PARSER] Do not show prompts in expandstr
Upstream patch: Date: Thu, 27 Dec 2007 13:57:07 +1100 [PARSER] Do not show prompts in expandstr Once I fixed the previous problem it became apparent that we never dealt with prompts with new-lines in them correctly. The problem is that we showed a secondary prompt for each of them. This patch disables prompt generation in expandstr.
