C:\...\_Projects\Documentation>svn --version
svn, version 1.8.1 (r1503906)
   compiled Jul 22 2013, 19:58:17 on x86-microsoft-windows

Copyright (C) 2013 The Apache Software Foundation.

The following repository access (RA) modules are available:

* ra_svn : Module for accessing a repository using the svn network protocol.
  - with Cyrus SASL authentication
  - handles 'svn' scheme
* ra_local : Module for accessing a repository on local disk.
  - handles 'file' scheme
* ra_serf : Module for accessing a repository via WebDAV protocol using serf.
  - handles 'http' scheme
  - handles 'https' scheme

When using a file:/// URL with the drive letter being a mapped network share or a SUBST 
drive letter, and the root of the repository being at the root of the mapped/SUBSTed drive, 
the first character of the path of subdirectories in the repository is lost.

The mapped drive was reported via TSVN 1.8.1 on Windows XP, the SUBST drive letter on 
Windows 7 64-bit. Steps to reproduce:

PS R:\> svnadmin create LocalTest
PS R:\> svn co file:///r:/LocalTest r:\TestOne
Checked out revision 0.
PS R:\> cd TestOne
PS R:\TestOne> mkdir FirstChild


    Directory: R:\TestOne

PS R:\TestOne> svn add FirstChild
A         FirstChild
PS R:\TestOne> svn ci -m "First Commit"
Adding         FirstChild

Committed revision 1.
PS R:\TestOne> cd ..
PS R:\> svn ls file:///r:/LocalTest
FirstChild/
PS R:\> subst S: r:/LocalTest
PS R:\> dir s:


    Directory: s:\

PS R:\> svn co file:///s:/ r:\TestTwo
A    TestTwo\FirstChild
Checked out revision 1.
PS R:\> svn co file:///s:/FirstChild r:\TestThree
svn: E160005: Target path '/irstChild' does not exist
PS R:\> svn co file:///r:/LocalTest/FirstChild r:\TestFour
Checked out revision 1.
PS R:\> svn ls file:///s:/
FirstChild/
PS R:\> svn ls file:///s:/FirstChild
PS R:\>

I can check out from the actual filesystem path (file:///r:/LocalTest/FirstChild) but not 
the path using S: as the repository root (file:///s:/FirstChild), but svn ls behaves 
correctly:

PS R:\TestFour> svn add file.txt
A         file.txt
PS R:\TestFour> svn ci -m "new file"
Adding         file.txt
Transmitting file data .
Committed revision 2.
PS R:\TestFour> svn ls file:///r:/LocalTest/
FirstChild/
PS R:\TestFour> svn ls file:///r:/LocalTest/ -R
FirstChild/
FirstChild/file.txt
PS R:\TestFour> svn ls file:///s:/ -R
FirstChild/
FirstChild/file.txt
PS R:\TestFour>
