minimum file padding causes issues with piping to other programs

[digitalsushi]

On https://github.com/jdberry/tag/blob/master/Tag/Tag.m#L385 there is some padding that gets put into the file output. This causes the filename to be invalid.

$ touch test1 test2
$ tag -a demo *
$ tag -m demo *
test1                          
test2                          
$ tag -0 -m demo * |xargs -0 ls -l
ls: test1                          : No such file or directory
ls: test2                          : No such file or directory

If I remove the padding and recompile, the program works as I expect it to. I am not a developer, and this is my first submission so please be kind if my report is bogus or my description poor. Regards!

@digitalsushi Fixed, I think. Thanks for the report.
