Managing system configuration with hg?

The newlines will be lost:

    $ printf "a b c\ndef\n"
    a b c
    def
    $ foo=$(!!);echo $foo
    a b c def

It's possible to work around this in several ways, eg $IFS or
by doing the indentation in the status=$(...) itself.  Each
has its tradeoffs, and this was just a quick hack anyway.
I've spent more time writing this email than on the script
itself.  I wasn't striving for perfection :-)
