Process <prompt> tags in mit-kerberos

when we have a command followed by prompts:
command
<prompt>command:</prompt> instr
...
we want to transform to:
command << PROMPT_EOF
instr
...
quit
PROMPT_EOF.
This patch implements this. The problem is that the <prompt>
tags may occur in several consecutive <screen> ones. So we create
a fragment tree and process it recursively.
