			When "cat-file -p" prints commits, it shows them in their raw format, since git's format is already human-readable. For tags, however, we print the whole thing raw except for one thing: we convert the timestamp on the tagger line into a human-readable date. This dates all the way back toa0f15fa(Pretty-print tagger dates, 2006-03-01). At that time there was no other way to pretty-print a tag. These days, however, neither of those matters much. The normal way to pretty-print a tag is with "git show", which is much more flexible than "cat-file -p". Commita0f15faalso built "verify-tag --verbose" (and subsequently "tag -v") around the "cat-file -p" output. However, that behavior was lost in commit62e09ce(Make git tag a builtin, 2007-07-20), and we went back to printing the raw tag contents. Nobody seems to have noticed the bug since then (and it is arguably a saner behavior anyway, as it shows the actual bytes for which we verified the signature). Let's drop the tagger-date formatting for "cat-file -p". It makes us more consistent with cat-file's commit pretty-printer, and as a bonus, we can drop the hand-rolled tag parsing code in cat-file (which happened to behave inconsistently with the tag pretty-printing code elsewhere). This is a change of output format, so it's possible that some callers could considered this a regression. However, the original behavior was arguably a bug (due to the inconsistency with commits), likely nobody was relying on it (even we do not use it ourselves these days), and anyone relying on the "-p" pretty-printer should be able to expect a change in the output format (i.e., while "cat-file" is plumbing, the output format of "-p" was never guaranteed to be stable).
