# Description: Fuzzy search multiple locations read-in from a path-list file
# (or $PWD) and open the selected file's dir in a smart context.
# Dependencies: fzf, fd (only for multi-location search)
#
# Details: Paths in list file should be newline-separated absolute paths.
# Paths can be file paths; the script will scan the parent dirs.
#
# The path-list file precedence is:
# - "$1" (the hovered file) if it exists, is plain-text and the
# first line points to an existing file
# - "$LIST" if set below
# - "$2" (the current directory) [mimics plugin fzcd behaviour]
#
# The path-list file can be generated easily:
# - pick the (file)paths in picker mode to path-list file
# - OR, edit selection in nnn and save as path-list file
#
# The plugin clears nnn selection as the user can be tempted to delete
# duplicate files after finding copies and remove selection by mistake.
#
# Shell: POSIX compliant
# Author: Anna Arad, Arun Prakash Jana
