The patch below implements the following:
- --write-batch now accepts a prefix as a parameter instead of generating a
timestamp suffix. --read-batch has also been changed to treat its argument
as a prefix. Updated the documentation regarding this change.
- the rsync_argvs file created now optionally uses the first parameter
supplied as the target directory.
Btw, I have not seen --read-batch with a target directory different from the
one supplied to --write-batch fail.
- In batch.c, staticized some variables.
- Shortened the code in a few places.
- Added/modified a few comments.
- Fixed a few function prototypes.
- In main.c, removed some now unused variables.
Also, see the test script and sample session below.
