uploading to a directory that does not exist should create the directory

[jezra]

example:
bzr upload ftp://<email address hidden>/www/bazaar/test_code
fails if the bazaar directory does not exist

[EmmaJane (emmajane)]

At a minimum the error message should be made more useful. Currently it reads as follows:

$ bzr upload sftp://<email address hidden>/~/path/to/directory
No uploaded revision id found, switching to full upload
Uploading myfile.info
bzr: ERROR: No such file: 'path/to/directory/myfile.info.tmp.1236970319.404656887.1458.1866393847': [Errno 2] No such file

It would be more useful if this error message was something like, "Target directory not found. Please create the parent directory before uploading your files."

+1, the error message is quite confusing.

Perhaps a --create-prefix option can be supported, similar to what "bzr push" supports.

I'd rather not see "bzr upload" automatically creating the directory, since that can have unexpected side-effects, e.g. if you make a typo in the URL.

I agree with Jelmer and emmaJane:
- the error message should be clearer,
- we shouldn't create without being explicitly told to do so,
- --create-prefix is the way to go.
