Atlassian's markup seems to interpret a commonly used grammatical construct, dashes (i.e. pairs of double-hyphens), to imply strikethrough (like this) is desired. Dashes are a commonly used grammatical construct–to emphasize some text or provide in-line explanation–so, it's unfortunate that Atlassian syntax seems to have co-opted them... Is this a bug in how hyphens (the strikethrough indicator) are interpreted? Atlassian's markdown interpreter seems smart enough not to understand that a very-hyphenated-phrase is not a call for strikethrough...
