The previous implementation used to replace the contents of the buffer with whatever the `formatcmd` was returning, regardless of the exit code of the command, which led to the buffer being wiped out on error. This commit does the formatting in a temporary file, and only replaces the current buffer with the contents of the -formatted- temporary file if the `formatcmd` returned successfully. Fixes #1357
