i get that. what i was trying to say is that overrides for the "t-dsl"
profile (with hyphen) are now, obviously, "ppp_t_dsl_mode" and/or
"ppp_t_dsl_nat".  to me, it is somewhat confusing. another (pretty
weak :) argument is that all ".-/+" characters are mapped onto single
"_"  character. this could potentially create a collision in variable
names. i realize that you have done exactly the same thing as in
get_if_var() in network.subr. are there any examples of network
interface variable names that are not "shell clean"?

i'm still not sure :) however, please do not take it as an objection
:) since we already have similar code (and no one, including me,
complained :), it probably makes more sense to do the same here.
