Extraneous tab inside output of tune2fs

[hochl]

I recently found two stray tabs inside the output of tune2fs -l. Since these are the only two tab characters in the output, I guess this is a mistake that was introduced in commit 41a5afa87 (Theodore Ts'o 2008-04-20 16:10:07 -0400 363). I created a patch to replace them with spaces like in all other fields and attached it to this issue. ls_c.patch.gz

@hochl I came across this today as well. I converted your patch into a PR: #169
