Invoking nnn with:

nnn dir
nnn ./dir
nnn dir

wouldn't allow user to navigate to parent directory.

Add keybind 'Ctrl-k' to copy the absolute path of the file under the cursor if environment variable NOICE_COPIER is set.

1. Highlight the currently selected item in reverse video.
2. Fix: remember the current item when toggling detail view.

noice truncates the cwd string dynamically. If the numbers of columns is lesser than the length of the path, cwd is truncated so that the correct path cannot be resolved. We should try to resolve the full path instead.

B - Block Device
C - Character Device
D - Directory
E - Executable
F - Fifo
L - Symbolic Link
R - Regular File
S - Socket

1. The detailed view shows file type and size using keybind 'd'. Disabled by default.
2. Option 's' sorts dir entries by descending order of size.

The contents of the directory may be changed from the shell by adding or deleting content. Permissions may have changed too. We must re-populate the contents of the current directory.

Once set, the default filter is updated.  This means that
toggle dot will also work as expected when noice is executed
as root.

Based on discussion with Ypnose.

The magic.mgc file gets created in the local directory, opening
the global file throws unwanted messages. So we are using the o/p
of the file command to determine if the file is a plain text file.

Use mpv, fmedia, zathura.
Invoke libmagic to identify text files and open with vim.
Use xdg-open for unhandled mimes.

NetBSD has its own curses implementation and initscr() does not
terminate with an error if TERM is not set properly.

Instead check the return value and exit if an initialization
error occurs.

It should be the size of the destination buffer, not the source.

In this case, both src and dest have the same size.

This is more descriptive for a global variable which
can easily be shadowed.

Nobody uses it and adds additional complexity.

The code was quite fragile.  As a first pass, use buffers of size
PATH_MAX and LINE_MAX accordingly until we simplify the overall logic.

Avoids weird things like /etc/.. when displaying cwd.

Also no need for cwd to be on the heap.
