Indenting doesn't work for custom functions

[rickyheijnen]

Describe the bug
When using the format document function, it doesn't keep the indenting of my custom functions. Indents of Smarty default functions such as {if} {foreach} or {for} are nicely formatted. But I have many custom functions like {tabset} or {tab} and their indent keeps being removed by Format document.

This is reproduced here for me as well. But I don't think it's a bug.
I've found that there is no problem if using smarty's native delimiter {} indentation, it only happens with custom tags or custom delimiters.
I strongly hope that the author can add custom delimiters. For example, my current project delimiter is {%%}. This project is very old, and it will be a big project to modify the delimiter.

I have a similar issue, I use {t}text{/t} to mark translatable strings, but the formatter breaks things up :

<div class="callout secondary">{t}No records found{/t}</div>

becomes

<div class="callout secondary">{t}No records found {/t}</div>

It is a big problem because now the translation string has a \n at the end, and it cannot be found anymore.
Would be nice if we could have a blacklist for specific functions, or at least doesn't try to format unknown functions

@aswinkumar863 could you please add the possibility to configure custom reservated words for identation?
