[PLUG] git: remove all deleted files from status report

[Rich Shepard]

I switched widget toolkits on a project and deleted all files for the former
approach. But, when I run 'git status' all the deleted files are shown and
overcome the v.t.'s scrolling range.

StackOverflow has several threads on this issue and most recommend using
'git add -u .' then committing the changes. I did this but the old deleted
files still overwhelm the status report.

Other proffered solutions used 'git rm ...' but none of those worked here;
there were command syntax errors that git didn't like.

I'm out of ideas and would like some new ones.
