This happens on current main, i.e. https://nest.pijul.com/pijul/pijul/changes/FY6SDCTOQGPHDS3UZ7HJAXEDDYYLAFQXEQSSEWF62TK25MGRWJHQC.

In an empty directory:

❯ pijul init
Repository created at […]
❯ touch test.txt
❯ pijul add test.txt
Tracked 1 path(s)
❯ pijul record -m "add test.txt"
<save and quit editor>
Error: Cannot parse change

It works using pijul record -m "add test.txt" -a, however.

Continuing from the above,

❯ echo "One
  Two" > test.txt
❯ cat test.txt
One
Two
❯ pijul rec -m "add lines"
<save and quit editor>
