There was another link that I should have included earlier:

https://selenic.com/hg/help/templating

(also available if you run "hg help templating")

There appear to be a few options for indenting:

tabindent
Any text. Returns the text, with every non-empty line except the first
starting with a tab character.

fill(text[, width[, initialident[, hangindent]]])
Fill many paragraphs with optional indentation.

indent(text, indentchars[, firstline])
Indents all non-empty lines with the characters given in the
indentchars string. An optional third parameter will override the
indent for the first line only if present.

Hope that helps,

Simon
