cargo, alpha.37.

I’ve invented tricky scenario, git-mercurial-darcs detected me and fired.

If remove steps “AAA-ZZZ” pijul can detect a file compression-replace too.

$ rm -rf p1
$ pijul init p1
$ cd p1
# AAA

$ vim a
$ cat a

$ pijul ls

# ZZZ
$ cp /bin/date a
$ pijul diff --short
R a
$ pijul record -am"."

$ cd p1
$ cp /bin/date .

$ pijul rec -am"."

This allowed me to discover that Windows is using January 1st, 1601 as the reference time for its modification files. I guess the intent is to look like they’re centuries ahead of Unix. Didn’t do the trick for me though…
