Can Mercurial use .hgignore to forget files?

Question

I forget to place the correct .hgignore into my project and am now confronted with many useless files in my repository. As these files are already under source control .hgignore will not pick em up.

Is there a way for hg to forget all files matched by .hgignore?

Answer 1

filesets awesomeness (requires 1.9):

hg forget "set:hgignore() and not ignored()"
