* Preserve code blocks in templates.Normalizer
Currently, if templates.LongDesc function is invoked multiple times
for a string including a code block, this code block is converted to
invalid code block.
The reason of this issue is that blackfriday package, which templates package uses, relies on
4 * indentation to detect code blocks. This PR always preserves
4 * indentation in code blocks to always detect it code blocks in also
post invocations.
* Add indentations to test for code blocks
* Use strings.repeat for repetition
