Less command keeps waiting for something when no input is given

Created by: blasrodri

Reproduction: When being on the terminal write less + ENTER

Expected behavior: Error message like Missing filename ("less --help" for help)

Actual behavior: It keeps on waiting for an IO operation that is never resolved.

Build information:

[output of rustc -V, git rev-parse HEAD, qemu-i386 -version, uname -a, etc.] In the VM it says: ion: command not found rustc
