[Pkg-rust-maintainers] Bug#1134488: /usr/bin/batcat: batcat color don't play nice with heredoc syntax

[Wesley Schwengle]

Package: bat
Version: 0.26.1+dfsg-1+b1
Severity: important
File: /usr/bin/batcat
X-Debbugs-Cc: wesley at schwengle.net

Dear Maintainer,

batcat claims to be a drop-in replacement for cat. That may be true, but it
acts really weird in some cases where you don't want this to happen:

$ which cat
cat: aliased to batcat
$ cat > foo.xml  <<'OEF'
<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
  <debug-overrides>
    <trust-anchors>
      <certificates src="@raw/opndev_ca" />
      <certificates src="system" />
    </trust-anchors>
  </debug-overrides>
</network-security-config>
OEF

$ command cat foo.xml | od | head -10

$ file foo.xml
foo.xml: XML 1.0 document, ASCII text

I consider this a bug, as this should be standard behaviour from cat that is
breaking assumptions with batcat.

Cheers,
Wesley
