Not sure how the wrapperscript would fit into the workflow, but I came up with 
this:


#!/usr/bin/env bash
# spc2tab - Convert leading spaces into tabs
# Required: sed
# Usage: spc2tab <file
nanoconf=~/.nanorc s='[[:blank:]]'
tabsize=$(grep -eo "^$s*set$s+tabsize$s+[1-9][0-9]*" "$nanoconf" |tail -1 |grep 
-o '[0-9]*$')
# Use given tabsize or 8 as (nano) default
tabsize=${1:-8}
spc=$(printf '%*s' $tabsize) tab=$'\t'
sed ":a;s@^\($tab*\)$spc@\1$tab@;ta" </dev/stdin
