We usally indent this like so:

cd corrupted &&
echo one >file &&
git add file &&
...

I think this is a bashism. On dash, I get the following:
genre ok % dash -c 'foo=abcdefg; echo ${foo:0:2}; echo ${foo:2}'
dash: 1: Bad substitution
Yeah, it is. You can do it easily with 'sed', of course, but if you want
to avoid the extra process and do it in pure shell, it's more like:
last38=${REV#??}
first2=${REV%$last38}
rm -f .git/objects/$first2/$last38
Is it "HEAD points to non-existent object" or ".git/HEAD contains junk"?
In both cases there are simpler solutions than to remove an object. For
example, `echo "$_x40" >.git/HEAD` or `echo "this is junk" >.git/HEAD`?
