That's actually insufficient for .texi changes.  The info and html files 
are both produced by makeinfo (that's the name of the program; don't 
confuse it with "make info", which calls it!) with different flags, and 
thus it's unlikely that one will find errors that the other doesn't.

However, the dvi files are produced by texi2pdf, which handles a number 
of things quite differently, and often has errors that don't show up in 
the html or info production.

Thus, a reasonable minimum amount of testing for the documentation is 
"make dvi" and either "make info" or "make html".  Of course, to be 
fully certain you can run all three, but if you're only doing two, "dvi" 
is not the one to drop.
