ctx.files() - the files changed in the changeset
so a deleted file would appear in ctx.files(), but you cannot get a
filecontext for it since it does not exist in that changectx.
if you want files that do exist in the changeset
for filename in changectx - loops over all files in the changeset (in
sorted order)
"for file in c: c[file]" is enough to go through the files
