Feature request: automatically trim indentation

[DrKGD]

Would it be possible to include an autogobble (I was thinking of lstautogobble package for lstlisting, LaTeX) flag onto the silicon binary?

E.g. of source code

			local _status = { }
				-- Left components
				_status[1] = { }
					table.insert(_status[1], ux.half_sx)
					table.insert(_status[1], uc.editor.state)
					table.insert(_status[1], ux.half_dx)

Setting the initial indentation to the first actual line of code

local _status = { }
	-- Left components
	_status[1] = { }
		table.insert(_status[1], ux.half_sx)
		table.insert(_status[1], uc.editor.state)
		table.insert(_status[1], ux.half_dx)

It is surely possible with the aid of external tools, for example the following one-liner:

1. Greps, thus retrieve only the indentation characters
2. Get the least possible amount
3. With cut, make the line start from the nth character (cut -c "${nth}-") instead

cut -c "$(grep -oP '^\t*' testcase | awk '{ print length+1 }' | sort -nu | head -n1)-" testcase
