This will hopefully be resolved when somebody integrates the record 
functionality into the core and adds hg qrefresh --interactive
The way I have there in the parenthesis is really the most generic-catch 
all way to do it. There are several shortcuts already:
"hg qrefresh" if you want to just add everything in the working copy 
into the current patch
"hg qrefresh --short" if you want to add only whatever is in the files 
that are in the current patch
"hg qrefresh -X glob" to exclude files matching glob, ...

The point being that you could very well stop whatever you might be 
doing at any point along the way and go in a different direction.
