`--show-item-count` ignored in `--non-interactive` mode

[vmikk]

First of all, thanks for developing gdu, it’s a fantastic tool!

Describe the bug

When running in non-interactive mode (-n), the --show-item-count (-C) flag appears to have no effect: item counts are not displayed.

To Reproduce

Simple example:

tmp=$(mktemp -d)
mkdir -p "$tmp"/{a,b,c}
touch "$tmp"/a/{1..5}
touch "$tmp"/b/{1..10}
touch "$tmp"/c/{1..15}

Interactive (counts visible):

gdu -C "$tmp"

Non-interactive (counts missing):

gdu -n -C "$tmp"

Output

4.0 KiB /c
4.0 KiB /b
4.0 KiB /a

Expected behavior

In non-interactive mode, each directory line should include the item count (like in interactive mode), enabling use in scripts.

System (please complete the following information):

• OS: Fedora 42
• Terminal: Konsole / Ghostty
• Version: gdu v5.31.0 (Built time: Fri Jun 6 11:27:29 AM CEST 2025, Built user: dundee)

Additional context

If item counts are intentionally interactive-only, a note in the help/docs would be great.
Otherwise, supporting --show-item-count in --non-interactive mode would be very useful.
