hgview #9979 broken layout in case of rename of long filepath [validation pending]

explanation : adds, deletes and renames are shown in an intermediate zone betwen revision info and diff

the width of the whole column seems to be constrained by this line's width

in case of long_name (renamed from other_long_name) it's a problem (the File column may become out of reach)
