[jitendranalwaya]

Problem Description: In dijit/_editor/plugins/LinkDialog, URL input is validated, so unable to create file link if first folder contain underscore(-). Its showing error "The value entered is not valid". Steps to reproduce -

1. Open ​https://dojotoolkit.org/reference-guide/1.10/dijit/_editor/plugins/LinkDialog.html
2. Click on Run button (Under Examples section)
3. Click the link icon to open the Link Properties dialog.
4. In the URL field, attempt to type "​file:///C:/abc_test/xyz.txt"
5. It shows the warning message 'The value entered is not valid'.
6. You cannot create the link.

Validation passed for below links-

​file://localhost/C:/abc_test/xyz.txt

​file://localhost/C:/abc/xyz.txt

​file:///C:/abc/xyz.txt

Validation failed for below link-

​file:///C:/abc_test/xyz.txt

Expected behavior: The validation of the url should accept the underscore

Actual behavior: The url cannot be saved because of an validation error "The value entered is not valid"

If dojo permitted ​file://localhost/C:/abc_test/xyz.txt then, Why not permitted to ​file:///C:/abc_test/xyz.txt ?
