templatekw: introduce showlatesttags() to handle {latesttag} keywords The keywords {changes}, {distance} and {tag} will be available on a future template method that will allow pattern matching against tag names. For consistency, these should be available on the existing {latesttag} keyword as well. I debated whether or not to add {tag} instead of just continuing with the existing {latesttag}. But it seems clearer not to have the same name for two distinct things (a list in the LHS of %, and an individual tag value on the right). The value of latesttags[0] is the date of commit for the cset to which the tag is applied (i.e. not the date the tag was applied), and therefore isn't made visible because it doesn't seem interesting. It appears that this is merely an internal implementation detail for sorting csets in a stable manner when there are different branches.
