The ; or the newline is not needed either.

Unfortunately it seems to be required. Travis CI generates a shell script
out of the yml file and I think they don't respect newlines or something...

OK.

I usualy avoid "echo <something-starting-with-dash>" as I'm not sure how
portable it is across variants of "echo". Maybe this one is portable
enough, I don't know. Perhaps printf, or cat << EOF ...?

I am curious. Do you have an example on what platform echo "-something" 
could go wrong? I wasn't aware of such an issue.

echo can, but doesn't have to implement non-POSIX options. For example,

  $ dash -c 'echo -e foo'
  -e foo
  $ bash -c 'echo -e foo'
  foo

This is a good reason to avoid

  echo "$string"

if $string is a user-supplied string.

I don't know if any shell have issue with --------, but I wouldn't be
surprised if some implementation complained with "invalid option
---------".

But it is also likely that I'm the one being paranoid and your code is
fine ;-).

test -s Documentation/git.html &&
test -s Documentation/git.1

Great idea. Added to v2! The && is not necessary as Travis runs this script with "set -e".

Maybe I'm doing too much Python, but "explicit is better than
implicit" ;-). I'd keep the && in case someone ever moves the code to a
script that doesn't have -e, but I'm really nit-picking here ;-).
