+    and uncommitted changes in an otherwise-clean source tree.
 
     This means that purge will delete:
      - Unknown files: files marked with "?" by "hg status"
-     - Empty directories: in fact Mercurial ignores directories unless they
-       contain files under source control managment
+     - Empty directories: in fact Mercurial ignores directories unless
+       they contain files under source control managment
     But it will leave untouched:
      - Modified and unmodified tracked files
      - Ignored files (unless --all is specified)
      - New files added to the repository (with "hg add")
 
     If directories are given on the command line, only files in these
     directories are considered.
 
-    Be careful with purge, as you could irreversibly delete some files you
-    forgot to add to the repository. If you only want to print the list of
-    files that this program would delete, use the --print option.
