Fixes #36

@mholt Can you take a look on my PR? Thanks

What is the problem exactly?

[doggy8088]

@mholt There are some curl commands like this, which is multi-line command. Your current version can't handle multiline well. I fixed it.

curl -X POST https://api.easypost.com/v2/shipments \
     -u API_KEY: \
     -d 'shipment[to_address][id]=adr_HrBKVA85' \
     -d 'shipment[from_address][id]=adr_VtuTOj7o' \
     -d 'shipment[parcel][id]=prcl_WDv2VzHp' \
     -d 'shipment[is_return]=true' \
     -d 'shipment[customs_info][id]=cstinfo_bl5sE20Y'

I had a dig into what was going on here and added my notes to #36.

[mholt]
