Based on a first quick glance on the patch, it sure looks like you've got
things right.

Yeps, that's the only sensible way I can think of too. We should however
document that neither FTP nor HTTP always provide the size prior to the
download, so at times there will be files larger than the set maximum that are
downloaded anyway.

I can't think of any quirks a proxy might add to this case.

Information for next time: the .3 files are the source files for all the
man/help pages. They're written using NROFF format, which is a bit cryptic but
by seeing how the existing docs look you can easily figure out how to add new
similar sections or just edit existing ones. (Basicly, all files that are
present in CVS are "source files" that can be edited.)

The perl script is just responsible for putting together the huge help file
that makes --manual work for the command line tool. (It uses the texts from
the docs/curl.1 file and the docs/MANUAL files.)

It would totally rock if you could produce a few test cases for this new
option as well...
