            Bug ID: 8145
           Summary: regression: sa-learn error with backslash in Maildir
                    path
           Product: Spamassassin
           Version: 4.0.0
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Learner
          Assignee: dev@spamassassin.apache.org
          Reporter: david@mandelberg.org
  Target Milestone: Undefined

I use https://doc.dovecot.org/configuration_manual/plugins/listescape_plugin/
to enable some special characters in mailbox names, and it converts `.` to
`\2e`. After upgrading the Debian package for spamassassin from 3.4.6-1 to
4.0.0-6, I get the below error running sa-learn on Maildir folders with
backslashes in them. Adding an additional backslash seems to help though:

Oops, I'm actually not sure this is related to the upgrade at all. I came
across this bug while trying to figure out what was causing another bug. But I
just realized that while debugging that one, I was running sa-learn in a
different way than I usually do. (I usually change into the Maildir folder and
run sa-learn with a path of `.`.) So I don't have any idea if this is a
regression or not.
