Infinite loop when selecting entry with certain width relative to window width about pathpicker

[jpalus]

Reproduces for me with:

$ mkdir test-git
$ cd test-git
$ git init
# create file with name long enough relative to window width
$ echo test > $(printf 'f%.0s' `seq $(($(tput cols) - 10))`).txt
$ git status | fpp
# try to select file with 'F'
