[Message part 3 (text/plain, inline)]

When editing a bash script with nested " and ` marks the color coding gets
confused, coloring most text as a string. Sample code to reproduce the color
coding follows (this code is debugged and runs as expected, so syntax should
be ok)


#!/bin/bash

function list-dir {
cat "$repo"/list
}

function init-repo {
mkdir -p "$repo"
touch "$repo"/list
}

function save-dir {
init-repo
dirname="`basename "$1"`"
dirhash="`dir-to-repo "$1"`"
saveline="$dirhash $dirname"
if [ "`grep -Fc "$saveline" "$repo"/list`" -gt "0" ]; then
echo "A directory with the same name and content is already in the
repository."
exit
else
echo "$saveline" >> "$repo"/list
fi
}

You may want to upgrade to Emacs-23 where this has been fixed,
