Warning: this is the first hledger feature which can alter your existing
journal data. You can now edit, or ERASE, the (top-level) journal file
through the web ui, and there is no access control. A numbered backup of
the file will be saved at each edit, in normal circumstances.
Currently this is just the journal and timelog file formats. This is more
scalable, but when things go wrong there is no longer just a single parse
error. For now we'll just show the first error, the one from the journal
file parser.
