[Quilt-dev] [PATCH] quilt fetch: pull series and patches over ftp/http

[Brandon Philips]

I have seen a number of people posting patch series on ftp and http sites but
there is no good way of pulling these series into a tree, until now.  :)

example usage:

quilt fetch 
http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.2-rc2/2.6.2-rc2-mm1/broken-out/series

This will download all patches in the series file and import them into the tree
in the proper order.

KNOWN BUGS: My regular expression in check_line doesn't work for series entries
with -p flags like this one: http://ifup.org/patches/test/series .  Does anyone
have any idea how to fix this?  Surprisingly this works:

echo io-fingerprinting.patch -p2 |  egrep -q 
'^\s*[_a-zA-Z0-9\.\-]+(\s\-p\s*[0123456789]?)?\s*$'; echo $?
