Function: texinfo-format-buffer

Process the current buffer as texinfo code, into an Info file.
The Info file output is generated in a buffer visiting the Info file
name specified in the @setfilename command.

Non-nil argument (prefix, if interactive) means don't make tag table
and don't split the file if large. You can use `Info-tagify' and
`Info-split' to do these manually. (fn &optional NOSPLIT)
