logtoprocess: add a test to show pager and ltp bad interaction The next changeset will fix the bad interaction between the pager and log-to- process. Add a test first to make the next changeset easier to understand. Differential Revision: https://phab.mercurial-scm.org/D4815

 Running a command triggers both a ui.log('command') and a
 ui.log('commandfinish') call. The foo command also uses ui.log.
 
 Use sort to avoid ordering issues between the various processes we spawn:
-  $ hg foo | cat | sort
-  
-  
+  $ hg foo
+  $ sleep 0.2
+  $ cat $TESTTMP/command.log | sort
   
-   (chg !)

+Try to confirm that pager wait on logtoprocess:
+
+Add a script that wait on a file to appears for 5 seconds, if it sees it touch
+another file or die after 5 seconds. If the scripts is awaited by hg, the
+script will die after the timeout before we could touch the file and the
+resulting file will not exists. If not, we will touch the file and see it.
