Junio C HamanoDiligent people save output from format-patch to files, proofread and edit them and then finally send the result out. If the resulting files are sent out with "git send-email 0*", this ends up sending backup files (e.g. 0001-X.patch.backup or 0001-X.patch~) left by their editors next to the final version. Sending them with "git send-email 0*.patch" (if format-patch was run with the standard suffix) would avoid such an embarrassment, but not everybody is careful.
After collecting files to be sent (and sorting them if read from a directory), notice when the file being sent out has the same name as the previous file, plus some suffix (e.g. 0001-X.patch was sent, and we are looking at 0001-X.patch.backup or 0001-X.patch~), and the suffix begins with a non-alnum (e.g. ".backup" or "~") and ask if the user really wants to send it out. Once the user skips sending such a "backup" file, remember the suffix and stop asking the same question (e.g. after skipping 0001-X.patch~, skip 0002-Y.patch~ without asking).
