# The time massaging regexes start with ^[^<]* because that ensures that they | |
# only operate before the first "<". That "<" will be the beginning of the | |
# author name, ensuring that we don't destroy anything in the commit message | |
# that looks like time. | |
# | |
# The log format uses } characters between each field, and `column` is later | |
# used to split on them. A } in the commit subject or any other field will | |
# break this. | |
