If I have a job called "My Cool Job", and I go to the Embeddable Build Status Plugin, and choose any Markdown build status, and paste it in a Markdown file (say README.md), it won't show the build badge.
The markdown code for the build status badge shows the badge for the job which has spaces in its name.
The markdown code for the build status badge does not show the badge for the job which has spaces in its name.
For a job called "My Cool Job" and branch "master" this is the Markdown generated:
[![Build Status](https://myserver.com/buildStatus/icon?job=My Cool Job/master)](https://myserver.com/job/My Cool Job/job/master/)
Note that the spaces in "My Cool Job" are not URL encoded. The spaces should be replaced with "%20".
