(texinfo)paragraphindent

Paragraph Indenting
-------------------

  The Info formatting commands may insert spaces at the beginning of the
first line of each paragraph, thereby indenting that paragraph.  You
can use the `@paragraphindent' command to specify the indentation.
Write an `@paragraphindent' command at the beginning of a line followed
by either `asis' or a number.  The template is:

     @paragraphindent INDENT

  The Info formatting commands indent according to the value of INDENT:

   * If the value of INDENT is `asis', the Info formatting commands do
     not change the existing indentation.

   * If the value of INDENT is zero, the Info formatting commands delete
     existing indentation.

   * If the value of INDENT is greater than zero, the Info formatting
     commands indent the paragraph by that number of spaces.

  The default value of INDENT is `asis'.

  Write the `@paragraphindent' command before or shortly after the
end-of-header line at the beginning of a Texinfo file.  (If you write
the command between the start-of-header and end-of-header lines, the
region formatting commands indent paragraphs as specified.)

  A peculiarity of the `texinfo-format-buffer' and
`texinfo-format-region' commands is that they do not indent (nor fill)
paragraphs that contain `@w' or `@*' commands.  Note: Refilling
Paragraphs, for a detailed description of what goes on.
