[PATCH v2] pre-push.sample: remove unwanted `IFS=' '`.

[Jim Hill <gjthill@gmail.com>]

Limiting the shell's word splitting breaks command substitution from
e.g. `git rev-list` output, the motivating example is

    range="$local_sha $(
            git for-each-ref --format='^%(refname)' refs/remotes/$remote
    )"
    # ...
    commit=`git rev-list -n 1 --grep '\bbad string\b' $range`

which fails with IFS=' ' because newlines aren't valid in commit id's
