directaccess: fix uses of commands.status() that don't go through flag parsing
When `commands.commit.post-status` is enabled, after commit/amend,
commands.status() is called without any revs argument, which means that status
gets None instead of an empty list like it would receive if the user had invoked
this on the commandline. With the `experimental.directaccess` config enabled,
this gets passed to `unhidehashlikerevs`, which didn't previously handle None,
but now should.

ATTENTION: logtoprocess runs commands asynchronously. Be sure to append "| cat"
to hg commands, to wait for the output, if you want to test its output.
Otherwise the test will be flaky.
Test if logtoprocess correctly captures command-related log calls.

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 fooba
$ sleep 1
$ cat $TESTTMP/command.log | sort
command
fooba
logtoprocess command output:
#if no-chg
$ cat $TESTTMP/commandfinish.log | sort
canonical: foobar
commandfinish
fooba exited 0 after * seconds (glob)
logtoprocess commandfinish output:
$ cat $TESTTMP/foo.log | sort
a message: spam
foo
logtoprocess foo output:
#endif
Confirm that logging blocked time catches stdio properly:
$ cp $HGRCPATH.bak $HGRCPATH
$ cat >> $HGRCPATH << EOF
> [extensions]
> logtoprocess=
> pager=
> [logtoprocess]
> uiblocked=echo "\$EVENT stdio \$OPT_STDIO_BLOCKED ms command \$OPT_COMMAND_DURATION ms" > $TESTTMP/uiblocked.log
> [ui]
> logblockedtimes=True
> EOF
$ hg log
$ sleep 1
$ cat $TESTTMP/uiblocked.log
uiblocked stdio [0-9]+.[0-9]* ms command [0-9]+.[0-9]* ms (re)
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.
