dispatch: ignore failure to flush ui
When the pager dies, we get a `SIGPIPE`. That causes
`error.SignalInterrupt` to be raised ` (from `ui._catchterm()`). Any
further writes or flushes will cause further `SIGPIPE`s and furhter
`error.SignalInterrupt`. If we write or flush outside of the
try/except that handle `KeyboardInterrupt` (which
`error.SignalInterrupt` is a subclass of), then control will escape
from the `dispatch` module. Let's fix that by ignoring errors from
flushing the ui.
I would have rather fixed this by restoring the stdout and stderr
streams when the pager dies, but it gets complicated because of
multiple ui instances (ui/lui) and different pager setups between
regular hg and chg.
This changes a test in `test-pager.t`, but I don't understand why. I
would have thought that all the output from the command should have
gone to the broken pager.
