doens't handle git commit callback properly

[e-cloud]

I have a git hook to check code style before commit(using eslint). If my code has error style, commit will not continue. If only have warnings, they will be shown, but commit can continue.

now standard-version will perform a release commit, which will also trigger the git hook.

However, it treat all stderr as illegal and just exit without continuing to perform git tag.

see the code

i think it should either prevent the git hooks when committing or improve the error handler
