Undocumented syntactic difference with mustache

[robinhouston]

I’m in the process of converting a project from mustache to handlebars, and I ran into a syntactic difference that isn’t documented in the differences section.

Mustache allows whitespace between the {{ and the #, >, ^, etc., which Handlebars does not. For example this snippet:

{{ ^ user }}{{ > header_not_logged_in }}{{ / user }}

had to be changed to:

{{^ user }}{{> header_not_logged_in }}{{/ user }}

to work with Handlebars.

It may be useful to mention this in the docs.

Hi. It would be great if you could create a PR that adds a bullet-point to the appropriate section. This certainly is noteworthy.
