[PATCH] global-ignores line too long in config

Currently, the global-ignores line in the autogenerated ~/.svn/config
file is 108 characters long! Ick. Instead it should wrap (and be a
nice example of continuation lines anyway).

This change isn't quite trivial, since the code that prints it uses
the SVN_CONFIG_DEFAULT_GLOBAL_IGNORES #define, and you don't want to
put the newline and # in that variable. I have a patch that "works",
but might be too ugly. What do you think?
