All good points. I guess I had my own set of use case assumptions,
different from these. I use copy'n'paste and auto-complete features
(like tab in bash) extensively, to avoid typos. Most of my
command-line use is also in the form of scripts, which use file
browser shells or "svk info" parsers to generate or convert path names
for me, so I end up having a lot of "-p" lines in these scripts. I
guess I also create deep directory structures far more frequently than
"normal" users. :)
    Your usage patterns make a good case for having some form of "pwd"
tracking in subversion clients, and "svn cd repo/path" commands. That
discussion should probably move to the thread suggesting there should
be an SVN "console mode"...

    Something in the history of all that is Posix must have lead to
"-p" not being the default in mkdir and cp, so I guess I'll bow to
that. Anyway, I guess my vote, if --parents isn't on by default, would
be to add the "-p" shorthand, since I do use it so often. "-P" would
also be acceptable. Using both "-p" and "-P" might be best. I must
admit, I didn't find it likely that it would become the default
behavior, but I thought it was worth debate. One of my devil's
advocate moments I suppose. I wonder if there's been any public
surveys about "mkdir -p" or "cp -P" usage patterns in the wild?
