[help-texinfo] Indenting a block of text

[Andreas Falkenhahn]

Hi,

how can I indent a specific block of text? I'm currently using @quotation / 
@end quotation
for this but it narrows both margins which I don't like. I just want to have 
some indentation
on the left side, not on the right side. Here's an example:

This is a line of normal text.
This is a line of normal text.
     This is a block of indented text.
     This is a block of indented text.
This is a line of normal text.
This is a line of normal text.

What command should I use to indent the text block in the middle?

Tks,

Andreas
