Controls the factors that are considered or ignored when using the Show Differences (File) command on the Tools menu.
Diff_Ignore = list of options
Ignores end-of-line differences, and displays all others:
Diff_Ignore = c-es-w-
The VSS Show Differences (File) command is used to display all the relevant changes to a file. This variable defines what is a relevant change. You can control four issues in this variable.
The format of the variable is a list of these four letters, with a dash after any variable that should not be ignored. In the preceding example (also the default), E is the only letter that is not followed by a dash; consequently, end-of-line characters are the only differences ignored.
