Here's a workaround that makes UPDATED redundant for 'svn log':
svn log --limit 1 URL
svn log --limit 1 URL@150
However, it would still be nice to have for 'svn info'.
I have needed UPDATED type functionality before, but a keyword/alias
seems awkward/inappropriate. Should it be more of a switch than a
revision alias?
svn log -r HEAD --find-last-changed URL
svn info -r 150 --find-last-changed URL
What about the case where your revision is between two revisions? Ex:
foo.java has two revisions, 100 and 200.
You specify '-r 150'.
You want log to report on r100 instead of the non-existant r150.
Your way works if you specify a Peg Revision:
svn log -r UPDATED URL@150
or would a switch be cleaner?
svn log -r 150 --find-last-changed URL
Instead of UPDATED, it might be better to match "svn info"'s "Last
Changed Rev:" entry, say CHANGED, or LAST_CHANGED, or even
LAST_CHANGED_REV to make it abundantly clear?

TAIL does sound better. I didn't see an enhancement request for TAIL in
the issue tracker, though.
A COPIED_PREV+1 (CPREV+1) could be useful for merge information. If you
branched from trunk:100, then you need to merge from trunk:101 to
trunk:HEAD. But anyone that lazy shouldn't be allowed to do merge
tracking.
CPREV/COPIED-1 isn't needed since the copy-from information is in the
TAIL/COPIED revision.

COPIED is the TAIL of the branch, so this isn't a problem. Which is
also why TAIL is a better name than COPIED.

Your request to have the ability to specify certain fields (which I
called a -fmt option ala ClearCase) would suffice. Ex:
svn log -r TAIL -fmt "%Cn:%Cr\n" URL
where '%Cn' is the copy-from name, and '%Cr' is the copy-from revision.
