Thanks!  I've pushed all of these patches.  All but one of them
were committed without any additional changes; and that one was
0006-Add-non-IRCv3-SASL-module-to-ERC.patch, where I just added
the missing entries for doc/misc/erc.texi and etc/ERC-NEWS to the
commit message.

What do you think about tweaking the last sentence to be more specific
about when calling `erc-update-modules' may still be needed, maybe
with a short example, please?

What do you think about adding a few short examples to the manual
showing the usage of each of the variants/mechanisms with a call to
`erc-tls'?  Kind of like the ones in "Connecting to an IRC Server"
that show how to use `:client-certificate' for instance.

Many thanks for all of your work on implementing and landing SASL
support for ERC, a feature that many ERC users (myself included)
have wished for and looked forward to seeing in ERC for years!
