slackbuilds_ponce/network/elinks/0002-gopher_index_queries.patch

#######################################################################
# elinks by default generates its own search query form when it sees
# a type 7 index entity. The problem is that it didn't read the
# served results page and instead generated another search page after
# you had entered the first. This patch fixes that and in my tests it
# seems to work so far.
