not copying the whole line after '%' character for some commands

[alkeryn]

so if i try to chose some command that has the "%" character, anything after that will be cut for some reason. some of those commands are

ffmpeg -f alsa -i default -flush_packets 1 $(date '+%d-%m-%y-%H_%M_%S').ogg
echo %hello%

if there is a command such as echo %%foo%%bar%% i'll get echo %foo%bar%
