The bug writing guidelines (URL above) don't mention how formatting works in bugzilla.
E.g., only by accident did I discover that
a space at the beginning of a line makes a box.
However
; a ":" doesn't do anything special there, as opposed to wikitext, etc.
Compare
http://core.trac.wordpress.org/wiki/WikiFormatting which tells us how to make our reports sharp looking.
However here on bugzilla.wikimedia.org it is just hit and miss. There is no list of formatting rules.
