The hgweb mercurial web interface on current Debian/Squeeze (mercurial-common 1.5.1-2) lists tab characters as-is in the diff view.

Every line is prefixed not only by a plus or a minus (unified diff), but also by file and line numbers. This can cause a tab (0x9) character to appear as a single space. This does not look nice.

The following patch can be applied to expand the tab character so the intentation looks right again.
