Since d1c5f2a (Add git-am, applymbox replacement., 2005-10-07), git-am would error out if the user gave it mbox(s) on the command-line, but there was a session in progress. Since c95b138 (Fix git-am safety checks, 2006-09-15), git-am would detect if the user attempted to feed it a mbox via stdin, by checking if stdin is not a tty and there is no resume command given. Re-implement the above two safety checks. Signed-off-by: Paul Tan <redacted> --- builtin/am.c | 15 +++++++++++++++ 1 file changed, 15 insertions(+)
