Hi,
I had some difficulty finding out what a minus sign does
in a Makefile. Attached patch suggests to add the word
to the text and the index, like it is done for tilde.
By the way, in HTML the at signs in the following two index
items look very different:
@ (in recipes): Echoing
@, and define: Canned Recipes
So I think the following change would be good:
-@cindex @@, and @code{define}
+@cindex @code{@@} and @code{define}
If so, then this would have to be done for several other
tokens too (+, -, ?, ...).
Regards,
Benno
