Some frontends stuff multi-line subscription content into a single
string with literal backslash-n sequences. The whole blob parsed as
one URI whose fragment swallowed the remaining links (1 node with a
garbage name instead of N nodes).
Normalize literal \r\n / \n to real newlines at the ParseProxyLines
entry, after format detection and before splitting. Real newline
input and single links are unaffected.
