bug#60784: 29.0.60; ERC 5.5: Don't interfere with non-module minor modes in erc-open

[J.P.]

Tags: patch

ERC currently takes ownership of any minor mode it encounters whose name
happens to be prefixed with "erc-" as long as its mode variable is set
locally in an ERC buffer. That is, it propagates the enabled/disabled
state to new `erc-mode' buffers, possibly by calling the namesake
minor-mode function. This makes sense for modes defined by "local"
modules, whether built-in or third-party. But other, non-module minor
modes that just happen to use the same top-level library namespace
should be left alone.
