Minimum size not compatible with template package

[alexandrestein]

• go 1.8
• Linux 64
• I using the package with templates
• I expect to see the template as it should :smiley:
• But I get the template with some special chars. It looks like bad decoding

The problem comes from the size limitation.

If the template package is used, it can calls Write multiple times with variable length. In any case the response writer must be the same for the all response inside the same request. So the package as is, is not good.

I made some modifications to prevent using different response writers on successive calls.

But the size limitation become pretty pointless with template or other handlers calling multiple times the Write function.

Looks like another recent PR may have caused some merge conflicts. Please clean those up and, if @adammck also gives blessing, I'll pull this in.

Yo, @adammck! Have a sec to put your :eyes: on this one? I'd like your 👌 before merging.

Sorry for the last-minute review, @jprobinson, but you did ask :smile: Feel free to dismiss if you'd prefer to get this merged and tidy things up later.
