[CentOS] command line file completion on CentOS 7

I have noticed on CentOS 7.2 that when I am doing command line
file TAB completion it behaves differently.

if I have a file /tmp/file 1.txt (notice the space)

when I do:

ls /tmp/file   and hit TAB it works

but if I do:

more /tmp/file and hit TAB it does NOT work.
What I get is
1.txt    file

versus just expanding to /tmp/file 1.txt

Why are they not the same?

Thanks,

Jerry
