Extend 'Reindent(format) lines' to other languages


One feature from the RStudio IDE that I use a lot is the ‘Reindent lines’ function.
With the rise of packages such as blogdown, which makes it more likely to be coding in another language (e.g. css, js, html, perhaps even SQL), it will be very useful if the ‘Reindent lines’ feature extend to those languages.
This applies to the Reformat feature as well but I have a feeling it is not used as often.
