We want to address these two strings in Bugzilla reports, so that the initial three asterisks "***" don't generate a bullet point in Phabricator:
| *** This bug has been marked as a duplicate of bug 123456 *** | *** Bug 123456 has been marked as a duplicate of this bug. ***
Compare https://bugzillapreview.wmflabs.org/T3347 with its original https://bugzilla.wikimedia.org/show_bug.cgi?id=65088
Note how some lines turn into bulleted lists in Phabricator with trailing asterisks, for example:
- Bug 65090 has been marked as a duplicate of this bug. ***
That's what happens when Phabricator sees leading **s in markup. In general I like that BZ's awful monospace turns into legible variable-width, and interpreting other ASCII elements conversion makes sense (e.g. quoted > lines become actual quotation). Ideally the conversion should avoid converting double- or triple-asterisks into bullets, or check to see if there are trailing asterisks on the same line and if so add the equivalent of <nowiki>.
Nothing directly corresponds to the latter message, I guess this is a textual representation of "Duplicate of this bug: 65090" ? If so maybe the representation could use something else than ***.
