Remove trailing, heading whitespace in tag values

[pschonmann]

For example
​http://www.openstreetmap.org/way/174293990/history ( look at changeset for more examples )

And + points when validator will remove trailing zeroes after floating point if not needed :)

Can you explain, what you want?

Hmm, after some investigation I assume you want that we don't upload useless spaces? This is implemented since version r5621.

Please don't report issues for long-time outdated versions.
