I'm using Pathogen, and am using git clones of xmledit and sparkup as bundles. These two plugins are automatically enabled for HTML, but I want to enable them for other HTML-like filetypes, such as Handlebars.
How can I automatically load ftplugins for HTML when I load a Handlebars buffer? I'm specifically looking for a solution that doesn't involve making any changes to the xmledit or sparkup git repos.
