+Zero or more `filemodify`, `filedelete`, `filename` and

may be included to update the contents of the branch prior to
creating the commit. These commands may be supplied in any order.
However it is recommended that a `filedeleteall` command preceed

See `filemodify` above for a detailed description of `<path>`.
+`filerename`
+^^^^^^^^^^^^
+Renames an existing file or subdirectory to a different location
+within the branch. The existing file or directory must exist. If
+the destination exists it will be replaced by the source directory.

+that contains SP the path must be quoted.

+A `filerename` command takes effect immediately. Once the source
+location has been renamed to the destination any future commands
+applied to the source location will create new files there and not
+impact the destination of the rename.
