<wbr> tags in bug text cause weird text-selection behaviour

[Martin Pool]

Launchpad seems to insert <wbr> tags into bug text, I guess so the page does not get too wide. However it inserts them into kind of strange positions. For instance, from https://bugs.launchpad.net/bzr/+bug/270738

&nbsp;&nbsp;File "/home/<wbr></wbr>jml/Code/<wbr></wbr>Bazaar/<wbr></wbr>bzr.dev-<wbr></wbr>2.5/bzrlib/<wbr></wbr>knit.py"<wbr></wbr>, line 1430, in iter_lines_<wbr></wbr>added_or_<wbr></wbr>present_<wbr></wbr>in_keys<br />
&nbsp;&nbsp;&nbsp;&nbsp;raise RevisionNotPres<wbr></wbr>ent(keys, self.filename)<br />
AttributeError: 'KnitVersionedF<wbr></wbr>iles' object has no attribute 'filename'</p>

You could equally well break after the identifiers.
