ash: [PARSER] Do not show prompts in expandstr

[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.
