🚀 Store .delta.lesshst in a location other than Home (Windows)

[rashil2000]

The get_delta_less_hist_file function stores the delta history file in the Home directory on Windows. While on *nix, it stores it in an XDG compliant directory.

delta/src/features/navigate.rs

Lines 84 to 96 in 93d3764

	#[cfg(target_os = "windows")]
	fn get_delta_less_hist_file() -> std::io::Result<PathBuf> {
	let mut path = dirs_next::home_dir()
	.ok_or_else(|| Error::new(ErrorKind::NotFound, "Can't determine home dir"))?;
	path.push(".delta.lesshst");
	Ok(path)
	}
	#[cfg(not(target_os = "windows"))]
	fn get_delta_less_hist_file() -> std::io::Result<PathBuf> {
	let dir = xdg::BaseDirectories::with_prefix("delta")?;
	dir.place_data_file("lesshst")
	}

Files beginning with a dot (.) are not hidden files on Windows - this is a *nixism. As such, the home directory looks cluttered when applications create these files.

I'd like to request that the this file be created somewhere else - the official place to store them is in ~/AppData/Local (rough equivalent of XDG_DATA_HOME). The function dirs_next::data_local_dir() can be used to get this.

Hi @rashil2000, thanks very much for opening this, and explaining the issue so clearly. I'm sorry I didn't reply until now, there has been a lot going on with delta! Let's discuss (if needed) in your PR.
