[help-texinfo] How to disable '_' to '_005f' transliteration in file names?

[Peter Simons]

Hi,

I'm in the process of migrating the documentation for the Autoconf
Archive to Texinfo format. In the process, I've run into a (minor)
problem and wonder whether there's a simple solution to it.

The documentation has a node per macro. These nodes are called, say
"ax_have_epoll". Now, when I use makeinfo --html to generate HTML pages,
the resulting pages are called "ax_005fhave_005fepoll.html". However,
for the sake of backwards compatibility with older versions of the web
site I'd need those files to be called "ax_have_epoll.html", i.e. I'd
like to disable the '_' to '_005f' transliteration.

Can that be done?

With kind regards,
Peter
