Russ Cox 657575a564 present: record info in AST for reproducing present inputs
Commands like .code now have a TemplateCmd method
that returns the original command.

The Text struct now has a Raw field set when Pre==true.
It contains the original indented text, without the tab "fixing".

This helps building tooling that reformats or rewrites present files.

For golang/go#33955.
