Fish 3.0 has an updated an more robust handling of unicode glyphs. Per
the original author of the INTERNAL_WCWIDTH flag, it was something of
misfeature, and they regret that NixOS came to rely on it.
Removes the flag from the Nix expression.
Flag was added originally to Nixpkgs in 68076b7d49
It is being removed entirely from upstream fish:
https://github.com/fish-shell/fish-shell/pull/5777.

# #
|
|
# Origin:
|
|
# This fish package was called with the attribute
|
|
# "useOperatingSystemEtc = true;".
|
|
#
|
|
# Purpose:
|
|
# Fish ordinarily sources /etc/fish/config.fish as
|
|
# $__fish_sysconfdir/config.fish,
|
|
# and $__fish_sysconfdir is defined at compile-time, baked into the C++
|
|
# component of fish. By default, it is set to "/etc/fish". When building
|
|
# through Nix, $__fish_sysconfdir gets set to $out/etc/fish. Here we may
|
|
# have included a custom $out/etc/config.fish in the fish package,
|
|
# as specified, but according to the value of useOperatingSystemEtc, we
|
|
# may want to further source the real "/etc/fish/config.fish" file.
|
|
#
|
|
# When this option is enabled, this segment should appear the very end of
|
|
# "$out/etc/config.fish". This is to emulate the behavior of fish itself
|
|
# with respect to /etc/fish/config.fish and ~/.config/fish/config.fish:
|
|
# source both, but source the more global configuration files earlier
|
|
# than the more local ones, so that more local configurations inherit
|
|
# from but override the more global locations.
|
|
|
|
