Special revisions PREV and COMMITTED are not file independent

[ColMelvin]

In SVN, when a list of files is given, along with the special revision PREV or COMMITTED, each file listed is always displayed, regardless of which commit it was changed in. Thus, displayed files can have different revisions in the output.

Git doesn't handle each file separately. If two files are listed on the command line, the first commit to have either file change is listed first. The subsequent commit may or may not contain the other file.

Addressing this issue will take a piecemeal approach to handling files, if it should be addressed.
