-margins- inherits whether variables are discrete or continuous from
the estimation command that precedes it (in your case -logit-). In
turn, the estimation command does its best to gauge whether included
variables are discrete or continuous.
To change the default behaviour, or indeed to be cautious, it is
advisable to use the unary operators to denote continuous and
indicator variables, "c." and "i." (as documented in -help fvvarlist-)
liberally.
The documentation for the -margins- command goes into great details on
these matters (-help margins-).
