Difference in Handlebars custom helper behavior from 1.0.beta.6 to 1.0.rc.1

[peterldowns]

Here's some server side JS using version 1.0.rc.1:

> var Handlebars = require('handlebars')
undefined
> Handlebars.VERSION
'1.0.rc.1'
> Handlebars.registerHelper('is_menu_item', function(x){console.log('is_menu_item_helper was run'); return true;});
undefined
> Handlebars.compile("{{#if is_menu_item}} hello {{/if}}")({});
''
> Handlebars.registerHelper('is_menu_item', function(x){console.log('is_menu_item_helper was run'); return 'true';});
undefined
> Handlebars.compile("{{#if is_menu_item}} hello {{/if}}")({});
''

Here's some client side JS using version 1.0.beta.6:

> Handlebars.VERSION
"1.0.beta.6"
> Handlebars.registerHelper('is_menu_item', function(x){console.log('is_menu_item_helper was run'); return true;});
undefined
> Handlebars.compile("{{#if is_menu_item}} hello {{/if}}")({});
is_menu_item_helper was run
" hello "

Which behavior is correct? I saw issue #289 which seems related, but I was relying upon the ability to use {{#if my_helper}} and have my_helper execute.

I have the same issue.

That behavior was an accident in previous versions of Handlebars and was removed :/
