[PATCH] ash,hush: drop pointer check before calls to show_history

[Ron Yorston]

show_history() checks that its argument in non-null so there's
no need to repeat the test at call sites.

function                                             old     new   delta
historycmd                                            25      17      -8
builtin_history                                       29      21      -8
