When "-" is used for standard input, the filename in the context/unified headers should be "-", not "/dev/stdin" #46
Description
When passing in "-" as a parameter on the CLI invokation to use the standard input for either of the input files, in conjunction with the -c or -u options, the filenames displayed should be "-", not "/dev/stdin", to be consistent with GNU's implementation:
echo foo > foo
echo bar | /usr/bin/diff -u foo -
--- foo 2024-04-03 18:55:48.837847038 +0200
