Interpretation of sftp and ftp URIs is inconsistent
---------------------------------------------------
Key: WAGON-325
URL: http://jira.codehaus.org/browse/WAGON-325
Project: Maven Wagon
Issue Type: Bug
Components: wagon-ssh
Affects Versions: 1.0-beta-7
Reporter: Andreas Sewe
Currently, a {{sftp}} URI of {{sftp://example.org/some/project}} essentially
translates to the following commands:
{quote}
sftp example.org
cd /
cd some
cd project
...
{quote}
But this is inconsistent with the interpretation of {{ftp}} URIs (as
standardized by <http://www.ietf.org/rfc/rfc1738> and followed by
{{wagon-ftp}}):
{quote}
ftp example.org
cd some
cd project
...
{quote}
Unlike {{wagon-ftp}}, {{wagon-ssh}} seems to treat the slash after
{{example.org}} as a part of the path already.
But at least for the {{ftp}} URI scheme this is wrong (according to RFC 1738):
{quote}
url-path
The rest of the locator consists of data specific to the
scheme, and is known as the "url-path". It supplies the
details of how the specified resource can be accessed. Note
that the "/" between the host (or port) and the url-path is
NOT part of the url-path.

{quote}
The url-path of a FTP URL has the following syntax:
<cwd1>/<cwd2>/.../<cwdN>/<name>;type=<typecode>
Where <cwd1> through <cwdN> and <name> are (possibly encoded) strings
and <typecode> is one of the characters "a", "i", or "d". The part
";type=<typecode>" may be omitted. The <cwdx> and <name> parts may be
empty. The whole url-path may be omitted, including the "/"
delimiting it from the prefix containing user, password, host, and
port.
The url-path is interpreted as a series of FTP commands as follows:
Each of the <cwd> elements is to be supplied, sequentially, as the
argument to a CWD (change working directory) command.
...

It would be great if an option could be added to {{wagon-ssh}} such that
interprets {{sftp}} in a RFC-1738-compliant fashion.
In particular, it would make the life of Maven users easier who do not have any
control over the location of their remote _home_ directory. Such a setup
(common with shared webhosting) makes it hard if not impossible to include an
absolute URI in one's POM (e.g.,
{{sftp://example.org//path/could/change/at/any/moment/some/project}}; note the
double slash) as a workaround.
