bug in pathalias (and fix)

[ekrell at ucla-cs.UUCP]

I found this problem when I introduced the csnet sites to the database
used by pathalias: the address for waterloo was stored as
"%s%%waterloo.csnet at csnet-relay.arpa" which works ok since the %% gets
translated into one % by sprintf(). The problem was in the address for
utzoo which was "utzoo!%s%waterloo.csnet at csnet-relay.arpa" (note only one
% here). When this was used by sprintf(), the % simply dissapeared.
  The problem was in pathprintf() in mapit.c. Here's a context diff bug fix:
