hgweb: revision history of a file omits revision which removes the file

[Jeff Walden]

Mozilla's Tracemonkey repository contains the file js/src/js.cpp.  While doing some archaeology recently, I was looking at its revision log:

http://hg.mozilla.org/tracemonkey/log/56128cae91c9/js/src/js.cpp

The particular problem I was tracking was not present in this revision:

http://hg.mozilla.org/tracemonkey/file/88d865ffd0a9/js/src/js.cpp

...and it appeared in this revision:

http://hg.mozilla.org/tracemonkey/file/bac73f9f2d2b/js/src/js.cpp

However, if you look at the commit message for the latter revision, you can see that it claims to be backing out a different revision:

http://hg.mozilla.org/tracemonkey/rev/55e23c647137

...and if you look at that revision, you can see that it removed js/src/js.cpp from the repository.  (Actually I think it moved the file, but as I understand it a move is a copy+remove, so remove's the important part.)

I think hgweb's revision display for a file should show revisions which remove that file.  Otherwise you get the weird situation where one revision shows a change to the file, and the immediate next listed revision adds the file anew.
