Feature request: manually set the syntax when reading from stdin

[kbtz]

It would be nice to have a option to set a file extension on the temporary file used to read from stdin, so we can handle syntax on these contexts too.

Here's an use case where I'd try to just print a function definition from type with syntax enabled:

alias ?=wat
function wat() {
	shopt -s extdebug
	declare -F $1
	shopt -u extdebug

	typedef=$(type $1)

	# Prints the debug output without highlighting
	echo "$typedef" | head -n1
	
	typedef=$(echo "$typedef" | tail -n+2)
	if [[ ! -z $typedef ]]; then
		if tty -s; then
			# Prints the function definition with syntax highlighting
			# '-s sh' produces /tmp/tmp.aP6kTGvrLT.sh so nvim reads it as a shell script
			echo "$typedef" | nvimpager -c -s sh
		else
			echo "$typedef"
		fi
	fi
}

Does that make sense?

Nvimpager supports all options that nvim also supports so you could do something like echo foo | nvimpager -c -- -c 'setf sh'. Does that work for you?

Very neat! Thank you!
