Re: @image in @example

[Patrice Dumas]

Hello,

There is an explicit condition that can be removed l 1832 in 
tp/Texinfo/Convert/HTML.pm.  The code dates back to the initial
implementation, so my guess is that I tried to do the same as in
makeinfo --html at that time or it came from texi2html.

Maybe the idea was that an image in preformatted environments (@example,
@display...) did not make sense?  Another reason could have been
validity of the resulting HTML, but I checked that img in pre should be
ok.

If nobody objects, I could make the change this week end.
