I agree. For plaintext stuff, you have to jump through hoops sometimes to get
it all nicely formatted. I have some hideously long <tmpl_loop><tmpl_if ..>
lines just to avoid all those added newlines.
There's a conflict between indenting your template for readability, and the
amount of whitespace that ends up in the output.
Take this simple snippet:
--- >8 ---
<tmpl_loop foo>
<tmpl_if bar>
* <tmpl_var baz>
</tmpl_if>
</tmpl_loop>
--- >8 ---
I'd really like this to generate:
--- >8 ---
* item 1
* item 2
* item 3
--- >8 ---
Instead, we get
--- >8 ---
* item 1
* item 2
* item 3
--- >8 ---
To get the desired output, you'd have to write your template like this:
--- >8 ---
<tmpl_loop foo><tmpl_if bar>* <tmpl_var baz>
</tmpl_if></tmpl_loop>
--- >8 ---
This gets painful pretty quickly.

While I'm not a TT user, I do like the [% var -%] syntax to suppress the
trailing newlines.
The main reason why I have never bothered looking into this, is that we use
H::T primarily for HTML generation, where the extra whitespace has no
significance (in fact, we run it through HTML::Tidy afterwards anyway).
