Grunt Shell + Heroku Push = No stdout - heroku

Question

Using Grunt to build, add, commit and push my code up to Heroku.
Build, add and commit are working great.
When I specify to "git push heroku master" in grunt shell I get no stdout while the process runs.
Here is the code in Grunt.js:
'git-push': {
command: 'git push heroku master',
options: {
failOnError: true,
stdout: true,
execOptions: { cwd: '../deploy'}
}
}
But I am only seeing the following when the process runs:
$ grunt push
Running "shell:git-push" (shell) task
Done, without errors.
I would like to see the output of the push while the push is in process.
Anyway to do this?
Update: Full grunt shell script
shell: {
'git-add': {
command: 'git --no-pager add .',
options: {
stdout: true,
execOptions: { cwd: '../deploy'}
}
},
'git-commit': {
command: 'git --no-pager commit -m "update"',
options: {
stdout: true,
execOptions: { cwd: '../deploy'}
}
},
'git-push': {
command: 'git --no-pager push heroku master',
options: {
failOnError: true,
stdout: true,
execOptions: { cwd: '../deploy'}
}
}
}
Final Grunt Shell (working):
shell: {
'git-add': {
command: 'git --no-pager add .',
options: {
stdout: true,
stderr: true,
execOptions: { cwd: '../deploy'}
}
},
'git-commit': {
command: 'git --no-pager commit -m "update"',
options: {
stdout: true,
stderr: true,
execOptions: { cwd: '../deploy'}
}
},
'git-push': {
command: 'git --no-pager push heroku master',
options: {
failOnError: true,
stdout: true,
stderr: true,
execOptions: { cwd: '../deploy'}
}
}
}

See:
How to make git diff write to stdout?
Adding --no-pager as an option, gives output.
git --no-pager <subcommand> <options>
Also, certain git commands write to stderr,as discussed here:
http://git.661346.n2.nabble.com/git-push-output-goes-into-stderr-td6758028.html
By including the flag and capturing stderr in the grunt task I was able to get output for the last part of the heroku push process (but not the part where the upload is tracked):
Fetching repository, done.
