Missing elements in Go Template lexer

[malcom]

Seems that the Go Template lexer do not support all "features" like assigned operator and multi-line comments. These elements in the rendered output are ignored and/or marked as a syntax error.

Code:

{{/* a comment */}}

{{/* a multi-line
comment
*/}}

{{ $variable := 1 }}
{{ $variable = 2 }}

Output:

Addressed in #401 :)
