Simplify _deindent()

Old code. Can't remember why it kept lines shorter than the indent as-is
instead of clearing them, but it's pointless for help texts, which is
the only place where _deindent() is used. s[n:] is safe even if
n >= len(s).

Help text parsing is pretty hot code too, so every bit helps.
