Fixed page overlap for file revision links in hgweb. This is another step to fix issue189, but currently the file revision numbers are read as changeset revision numbers, so the link will point to the wrong revision.

#!/bin/sh
hg init
echo This is file a1 > a
hg add a
hg commit -m "commit #0" -d "1000000 0"
ls
echo This is file b1 > b
hg add b
hg commit -m "commit #1" -d "1000000 0"
hg co 0
# B should disappear
ls
