I've written a simple stats script (in Python, using sax) that 
determines the longest way along with some other values of interest to 
me. For planet-070919:

Way with highest number of segments: 6348252 (5161 segments)

Full output attached. I'm currently working on converting it to the new 
planet dump format (API .5). If there's interest, I can post the script 
once I'm finished. It's rather simple, though.

The kind of information you seem to be after (<n> longest ways etc.) is 
easier to determine using an SQL database, though.

    longest value: u'Hallo anonymer Mapper! Bitte achte auf die Kleinschreibung von "name", "residential" usw, da sie wichtig f\xfcr die Renderer ist. Auch sollten Wege an Kreuzungen wirklich verbunden sein und nur Segmente enthalten, die in dieselbe Richtung zeigen.

    longest value: u"The old road was go here. But now there's building the M0, and they're dig a big hole there, so you have to go in the another way..." (len: 63, name: u'note', element id: 28079437)
  way:
    longest name: u'tiger:name_direction_prefix_1' (len: 29, element id: 5039416)
    longest value: u'GPX northbound and southbound in disagreement at south end of this way, so course in some doubt. The southbound seemed more curved, the northbound rather angular, so I considered the southbound to be the correct route. Also the Landsat looked slightly mor' (len: 29, name: u'note', element id: 2992102)
