After this:
https://secure.phabricator.com/D10392#bc342b5e
the ssh login wont work, giving the error:
Call to undefined function phutil_utf8_shorten() in /var/www/phab/phabricator/scripts/ssh/ssh-exec.php on line 88
I added a fix:
```
'U' => id(new PhutilUTF8StringTruncator())
->setMaximumGlyphs(128)
->truncateString(implode(' ', array_slice($original_argv, 1)))
```
instead of
```
'U' => phutil_utf8_shorten(
implode(' ', array_slice($original_argv, 1)),
128),
```
