Problem / Steps to reproduce

When launching fzf on a Linux TTY with TERM=linux, fzf seems not capable of drawing a border around the list of files.

I can reproduce this by:

• booting into a Linux system
• jump to a TTY or not boot into a desktop manager
• run fzf --margin=1 --border=rounded
• see missing border (sometimes "replaced" by the characters which were drawn at the same positions before)
