[stringtemplate-interest] indented IFs in STv4

[Nicola Musatti]

In my opinion if either an <if(x)>, and <else> or an <endif> are 
followed by whitespace until the following newline both the whitespace 
and the newline should be ignored; any newline following the if or the 
else body should be preserved. Thus:

[
<if()>
foo
<endif>
]

should print either

[
foo
]

or

[
]

while

[
<if()>
foo
<else>
bar
<endif>
]

should print either

[
foo
]

or

[
bar
]

On the other hand

[
<if(x)>foo<endif>
]

should print either

[
foo]

or

[
]

This approach is more natural than the current one when you need to 
insert alternate blocks of line and may also be used for inline 
conditionals.

Cheers,
Nicola Musatti
