ID 151160 - nuke.pluginAddPath() ignores backslashes as path delimiters

Problem summary:
The nuke.pluginAddPath() command doesn't treat the backslash '\' as a path delimiter, so if you add a Windows UNC style path, such as \\netshare\netshare\, then the actual plug-in path that is added will be the location where the command is run from. (i.e. the location of the init.py file containing the command.)

The nuke.pluginAppendPath() command does treat \ as a path delimiter, so UNC paths are added as expected.
 

Customer reported version:
nuke.11.1v4
 

Customer reported platform:
windows10
 

Steps to reproduce:
1. Add the following code to the init.py file in the .nuke directory:

​nuke.pluginAddPath('/tmp/test1')nuke.pluginAddPath('//tmp/test2')nuke.pluginAddPath('\tmp\test3')nuke.pluginAddPath('\\tmp\test4')nuke.pluginAppendPath('\tmp\test5')nuke.pluginAppendPath('\\tmp\test6')

2. Launch Nuke, and then open the Script Editor.
3. Run the following command: nuke.pluginPath()

Workaround:
Use forward slashes for the path. i.enuke.pluginAddPath("//unc/test/path")or use: nuke.pluginAddPath(path.replace("\","/"))

Nuke 9.0v1 - Windows 10, CentOS 7, macOS 10.13
 

Earliest version tested:
9.0v1 - This issue appears to be in all versions of the product
 

Expected behavior:
The path should be unable to break when setting nuke.pluginAddPath().
 

Actual behavior:
The path will break:

Example paths from steps:['/tmp/test1', '//tmp/test2', 'C:/Users/username/.nuke/\tmp\test3', 'C:/Users/username/.nuke/\\tmp\test4', 'C:/Users/username/.nuke', 'C:\\Program Files\\Common Files/Nuke/7.0/plugins', 'C:\\Program Files\\Common Files/Nuke/7.0/plugins\\Ocula', 'C:\\Program Files\\Common Files/Nuke/7.0/plugins\\Ocula\\3.0', 'C:\\Program Files\\Common Files/Nuke/7.0/plugins\\Ocula\\3.0\\VCRedist', 'C:/Program Files/Nuke7.0v10/plugins/user', 'C:/Program Files/Nuke7.0v10/plugins/icons', 'C:/Program Files/Nuke7.0v10/plugins', '\tmp\test5', '\\tmp\test6']

Note how the \tmp\test3 and \\tmp\test4 paths have been added with the .nuke directory, but not the \tmp\test5 and \\tmp\test6 paths, which were added with nuke.pluginAppendPath().
