     Schedule the indicated files for removal from the repository.
 
-    This only removes files from the current branch, not from the
-    entire project history.  If the files still exist in the working
-    directory, they will be deleted from it.  If invoked with --after,
-    files are marked as removed, but not actually unlinked unless --force
-    is also given. Without exact file names, --after will only mark
-    files as removed if they are no longer in the working directory.
+    This only removes files from the current branch, not from the entire
+    project history. -A can be used to remove only files that have already
+    been deleted, -f can be used to force deletion, and -Af can be used
+    to remove files from the next revision without deleting them.
+    
+    The following table details the behavior of remove for different file
+    states (columns) and option combinations (rows). The file states are
+    Added, Clean, Modified and Missing (as reported by hg status). The
+    actions are Warn, Remove (from branch) and Delete (from disk).

+    none   W  RD W  R
+    -f     R  RD RD R
+    -A     W  W  W  R
+    -Af    R  R  R  R
 
     This command schedules the files to be removed at the next commit.
     To undo a remove before that, see hg revert.
-
-    Modified files and added files are not removed by default.  To
-    remove them, use the -f/--force option.
