First, I guess that I should have marked this series of patches as
an RFC, but not for the reason you mentioned. This series changes
somewhat gitweb behaviour (patches 2/3 and 3/3 to be more exact) in
a way that before gitweb passed 'expanded' hashes to page / alternate
view links. For example before this series link to second page for
shortlog view starting from 'HEAD' passed literal sha1 for 'h' parameter,
ans second page started where first page ended. After this patch, if
refs have changed between viewing first page and clicking on the link
to second page, the resulting view would be second page of _new_ 'HEAD',
not of old (shown) 'HEAD'.

Second, you do not need to worry about adding parameters, because in 2/3
and 3/3 -replay is used to change view to the one which differs from
current by one parameter. Please take into account that some parameters
are just not important.
