[pmwiki-users] Disappearing backslashes?

A colleague is trying to include an example command line in a page, thus:

  openssl pkcs12 -export -in certificate.crt -inkey private.key 
-certfile int.pem -out certificate.pkcs12

Unfortunately, the command is too long to display without running off 
the right-hand side of the allowable text area.

The traditional way to break such a line, and indicate to the reader 
that the linebreak is not meant to be there is to finish the first line 
with a backslash, thus:

openssl pkcs12 -export -in certificate.crt -inkey private.key \
  -certfile int.pem -out certificate.pkcs12

However, if you try this, not only does the backslash not render, but 
returning to the edit window reveals it has actually disappeared from 
the page text.

Doubling the backslash works, sort of, but the next time the page is 
saved, it disappears again, leaving a single backslash in the text, 
which then disappears on the next edit....

I suggested using \, but the [@ ... @] stops that from rendering.

I did manage to find a previous example in the mailing list


but the fixes there don't work. I'm guessing that part of PmWiki or PHP 
has changed since then.

Any ideas, please?
