consider this (additional `-F' arguments deleted for brevity):

curl -F "action=flexsend" -s -A 'Lynx/2.8.5 (Compatible; ELinks)' --trace-ascii - http://www.spamcop.net/sc

  #== Info: getaddrinfo(3) failed for (Compatible;:80
  #== Info: Couldn't resolve host '(Compatible;'
  #== Info: Closing connection #0
  #== Info: getaddrinfo(3) failed for ELinks)':80
  #== Info: Couldn't resolve host 'ELinks)''
  #== Info: Closing connection #0

curl parses halfway into the option value of `-A' (user agent) and tries
to connect to the "host" after the first blank within this value, which
is completely wrong and fails.

  #== Info: About to connect() to www.spamcop.net port 80
  #== Info: Trying 212.105.197.134... == Info: connected
  #== Info: Connected to www.spamcop.net (212.105.197.134) port 80

incorrect: the bourne shell gives a quoted value to the `-F' option.
curl leaves the leading quotes attached to the form elements name and
adds the trailing one to the form elements value, thereby invalidating
both.

apart from a much needed bug fix, is there a workaround?
