Subject Re: Literal tab characters in templates
Date Thu, 24 Jan 2019 15:28:28 GMT
Since literal tabs look exactly like spaces, seems to me it's a bad
idea to try to include them in a template.
It's far to easy for another maintainer to accidentally remove it.

If it really is vital to use a tab instead of spaces, then ISTM that
it is better to make it obvious.
