non-obvious help needed

Hi,

Here is some texi source:

The "--help" renders in the menu with both hyphens.
The ones in the @subsection line and the later text
are unhelpfully "fixed up" and render with one hyphen.
How do I tell texi to leave my hyphens alone?

(The document is not hand edited, by the way.  I go
to a lot of trouble to figure out how the program
[unshar in this case] requests help and spread that
information around the document.  Should I just replace
all hyphens with "@-" for example?)

Thanks!  - Bruce
