I definitely want to see a resolution to this issue. Django templates
when white space matters (e.g. plain text emails) are painful. But, I
don't think adding {# to the end of lines is easy to understand at a
glance, it doesn't even convey a hint of meaning like "dnl" does, but
either option is pretty ugly to my eyes.
I'd personally like to see a new template tag that will switch on the
new behaviour, and a deprecation path for this to become the default.
Cheers.
Tai.
