Re: Path problem in prop_path_internal?

A long long time ago, in a galaxy far away, I wrote a couple of
functions, namely svn_path_get_absolute(), and
svn_path_condense_targets(), that were meant to deal with situations
such as this. The first takes a path and returns the absolute form of
it. The second takes a list of paths, and returns 1) The absolute path
that is common to all of the paths, and 2) A list of paths relative to
that common path. These were written to be able to find the directory
to call replace_root (or whatever we're calling it now) from when given
a situation like the following:

kevin@pilchie /home/kevin/projects/t1/$ svn commit iota ~/projects/t2

In this case, it will return with:
/home/kevin/projects
t1/iota
t2

It also does one other thing. If something is contained in another
target, it removes the redundant one, which works for commits and
updates, but isn't necessarily so great for propget. i.e.

kevin@pilchie /home/kevin/projects/t1$ svn propget . iota
will return only /home/kevin/projects/t1 since iota is in t1.

Anyway, take a look at them, and see if you can convince them to do what
you need. They are in svn_subr.h, and libsvn_subr/target.c
