bug with anchors containing special characters in split HTML output

[Thorsten Meyer]

Hi,

I think I have found a bug in makeinfo (makeinfo (GNU texinfo) 4.11 on
debian):

when
  - an @anchor name contains a special characters (I tried - and _)
  - output is sent to html (--html option) and
  - output is relocated to another directory (e.g. --output HTML)
then
  - references to this anchor do not work in html, because the html tag
does not point to the right directory (i.e. HTML instead of a directory
with the name of the info file)

example:
see attached texi file, process it with
    makeinfo --html --output=HTML first.texi
and try the the links in first chapter:
 - first link, no special character: works fine
 - second and third link, special character: does not work, reference to
wrong directory

regards

Thorsten Meyer
