record: handle translated prompt correctly
The prompt function would return 'y' or 'n' untranslated. This should
therefore not be compared to _('y') and _('n'). However, it turns out
that prompt could just as well return a good old Boolean.
#!/bin/sh
echo '% hg debuginstall'
hg debuginstall
echo '% hg debuginstall with no username'
HGUSER= hg debuginstall
# Happy End
