When performing a recursive status or update, any argments with whitespace
would be split along that whitespace when passed to the recursive invocation
of the update or status command.
This is caused by the special handling that sh provides to the $@ variable.
Status and update stored "$@" into a separate variable, and passed that
variable to the recursive invocation. Unfortunately, the special handling
afforded to $@ isn't given to this new variable, and word-breaking occurs
along whitespace boundaries.
We can use $(git rev-parse --sq-quote "$@") to produce a string containing
a quoted version of all given args, suitable for passing to eval. We then
recurse using something like `eval cmd_status "$orig_args"` instead of the
former `cmd_status $orig_args`. This preserves all arguments exactly as
given to the initial invocation of the command.

This patch ditches the quote_words function and uses
`git rev-parse --sq-quote "$@"` instead, as suggested by Jonathan Nieder.
