    kconfig: Avoid buffer underrun in choice input · 466de918
    Ben Hutchings authored
    commit 40aee729 ('kconfig: fix default
    value for choice input') fixed some cases where kconfig would select
    the wrong option from a choice with a single valid option and thus
    enter an infinite loop.
    
    However, this broke the test for user input of the form 'N?', because
    when kconfig selects the single valid option the input is zero-length
    and the test will read the byte before the input buffer.  If this
    happens to contain '?' (as it will in a mips build on Debian unstable
    today) then kconfig again enters an infinite loop.
