If I interpret things correctly then the below should work.

#d-i preseed/include_command \
#      string if [ "`hostname`" = bob ]; then d-i pkgsel/include 
string pluma gedit; fi

I suspect the substring "then d-i pkgsel/include string pluma 
gedit" might not be syntactically correct but indicates what I 
would like to do.
