# Description: Autodetects a nnn remote mountpoint (mounted with `c`) from any of its subfolders and allows unmounting it
# from there without first going back to the top or entering the remote name. Also works when hovering the mountpoint
# directly like vanilla `u`.
#
# Dependencies: fusermount
# Shell: POSIX compliant
# Authors: Kabouik & 0xACE
#
# TODO: Try better avoiding lazy unmount by forcing nnn context to leave the subfolder before fusermount.
# I tried `printf "%s" "0c$m" > "$NNN_PIPE"` but this would break nnn UI all the time, see #854.
