#83 sixel output corruption with longcat

[Yoichi NAKAYAMA]

I've observed longcat's sixel output is not displayed correctly on mlterm. (confirmed on macOS and Ubuntu Linux).
I've found commenting out L543 in common/c_sixel.c fixes the problem phenomenologically, but I don't know what is the correct fix.

You can get longcat program from https://github.com/mattn/longcat

I've confirmed the problem won't be reproduced after applying https://bitbucket.org/arakiken/mlterm/commits/a6e36763fc52cb27886c61facdee2014aca1aa3d
on my Ubuntu environment.

Thanks!
