This is a bug report for perl from perl-diddler@tlinx.org,
generated with the help of perlbug 1.39 running under perl 5.16.3.


-----------------------------------------------------------------
[Please describe your issue here]

Working with a program that uses a sub dir for a cache dir.

So that the path to the root of the cache will be the same as
the path on what I am caching, as soon as the cache module 
is opened, it cd's to the cache directory.

Later, I stepped past the point where I wanted to look at 
something so hit 'R' to restart.  Instead of restoring the
original directory and reading the script, the debugger 
simply tried to open the file from the wrong directory.

Seems like it would be best if it saved the starting directory
and 'cd'ed back to it before attempting to reread the original
program (which was in the current directory when the debugger
previously started the program).
