fzf-vim: missing dependency on bash
fzf.vim's preview window needs bash to work, without it, it'll show:
Preview window not supported (bash not found)
Error detected while processing function <SNR>5_lod_cmd[3]..fzf#vim#files[15]..<SNR>27_fzf[1]..<SNR>27_check_requirements[11]..fzf#exec[31]..function <SNR>5_lod_cmd[3]..fzf#vim#files[15]..<SNR>27_
fzf[1]..<SNR>27_check_requirements[11]..fzf#exec:
line 31:
E605: Exception not caught: Failed to run "fzf --version"
Press ENTER or type command to continue
and not work.
Porting it to ash might be doable, but in the meantime, adding a dependency on bash seems like the way to go.
