Add a configuration option to set a custom editor command,
different from EDITOR or VISUAL--those remain as defaults.
Implement substitutions allowing to convey cursor information
to VIM and Emacs (the latter of which is fairly painful to cater to),
and put usage hints in the configuration option's description.
This should make the editing experience a bit more seamless
for users, even though the position is carried over in one way only.
No sophisticated quoting capabilities were deemed necessary,
it is a lot of code already. The particular syntax is inspired
by .desktop files and systemd.
["/bin/sh", "-c", "vim +$2go \"$1\"", filename, position, line, column]
would be a slightly simpler but cryptic way of implementing this.
By default it's a mere thousand connections, which is unnecessarily
crippling our advertised ability to handle lots of them.
Thanks for the advice, Lennart.
First, we indexed the colour array without a required offset.
Second, the data type was too small and overflowed negative.
Detected during a refactor, which this is a part of.
I'm not entirely sure, but it looks like some people might not like
jokes about the Holocaust.
On a more serious note, the project has become more serious over
the 7 or so years of its existence.
With IRCv3.2 echo-message, each successfully sent message would
move us to the front of the list used for chanuser autocomplete.
Such behaviour seems useless.
Also abandon the idea of bumping on other kinds of messages.
Replaces the inaccurate Rec. 709 luma we used to use before.
This is the first feature here that requires libm, which doesn't
seem to be a particularly great sacrifice.
Moreover, I've rectified that the input isn't linear in sRGB,
and then was even normalized wrong for the luma formula.
It didn't make sense to have these unimplemented,
though perhaps += shouldn't enforce a set.
Sadly, autocomplete is fairly difficult for -= of multiple items.
So far it's only been mentioned in the NEWS file,
which is definitely not sufficient.
It would be good to move this kind of stuff out from README.adoc.
