[R] read.table: skipping trailing delimiters

I am trying to read a tab-delimited file that has trailing tab 
delimiters. It's a simple file with two legitimate fields. I'm using the 
first as row.names, and the second should be the only column in the 
resulting data frame.

Initially, R was filling the last column with NA's, but I was able to 
stop that by setting colClasses=c("character","character",NULL). Still, 
the data frame is coming in with an extra column, only now its values 
are set to "".

Is there any way to skip the trailing delimited field entirely? I've 
searched for an answer without luck.
