[PATCH 0 of 2] patchbomb: prompt fixes

[Christian Ebert]

Hi,

The first patch (a resend) allows the localization of the choices
for patchbomb's diffstat prompt by using ui.promptchoice().

Patchbomb's custom prompt was completely silent in
non-interactive mode. The second patch makes it show message and
prompt by catching potential errors before running it through
pure ui.prompt().
