Update ClearCase documentation

Review Request #5158 — Created Dec. 24, 2013 and discarded — Latest diff uploaded




Internal ClearCase post-review implementation from the beginnig use semicolon as separator. Because there is a bug in documentation people believe the implemntation is wrong. This change fix the documentation making straight forward that delimieter to separate file revisions and files in ClearCase --revision-range should semicolon ';' for both of them. This is alternative fix for #5154 which does not break forward compatibility.
