Thanks, I have a few comments about the documentation part:

If you run "make info", it will complain here, because you need to add
a comma after the right brace.

Is "flags" a good term?  I think "escape sequence" is better, e.g.:

  Any escape sequences specified as part of the prompt string are
  replaced with the corresponding strings each time the prompt is
  displayed.

                                              ^
Likewise, you need a comma here.

@code{set extended-prompt}.  And the same comment about "flags"
applies here as well.

The line inside @example should be broken into two, as it is too long.

This line needs an @exdent before it, because it is not a new
paragraph.

Aren't these ``..'' quotes left verbatim in the printed version of the
manual?  I think you need literal ".." quotes here, since they are not
converted inside @smallexample.
