Subject: Clear token before reading from input
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=99f2c1a2a64cac94ee56324fa25f8fba04cd1347;ds=sidebyside

Clear token before reading from input

Previously token would keep its value from the previous line when an empty
line was input, leading to unexpected behaviour.

No functional change

Resolves #119
