The % character is used to substitute the (background) job number
in csh/tcsh. Upon further research, the same mechanism is used in
bash, ksh, and the "real" sh, so if you used:

     svn diff %/branches/foo %/trunk

you'll end up substituting the process ID for the last command
that started with /branches/foo and /trunk, respectively (or get
a "no such job" error... :)

Also, sh/ksh/bash use it for some variable expansion stuff
(${parameter%word}, and bash adds math support where % is the
modulus operator...
