If stdio is not tty, conf_askvalue() puts additional new line to
prevent prompts are all concatenated into a single line. This care
is missing in conf_choice(), so a 'choice' prompt and the next prompt
are shown in the same line.
Move the code into xfgets() to take care of all cases. To improve
this more, echo stdin to stdout. This clarifies what keys were input
from stdio and the stdout looks like as if it were from tty.
I removed the isatty(2) check since stderr is unrelated here.
