Interrupt signals are already ignored.

vim.command is now "wrapped in a try-catch block" (it is really a pair of C functions). All vim exceptions are transformed into python ones, with vim.error class, and Vim:Interrupt is one of them. Code that was used to transform exceptions did change. You should now catch vim.error and match against error string: got_int apparently is not set inside :try/:catch because interrupts are transformed into exceptions thus code (present in VimTryEnd) that should be preferring raising KeyboardInterrupts over vim.error is useless.

And note that it is currently not possible to interrupt python code in most cases: signals are ignored and input is not polled when running python code.
