Description

Creating separate issue based on request in #10322 (comment)

I would like to have better visual presentation of an error message coming from a git hook. See screenshot below.

I can see two possible solutions
a) we allow HTML to be used in the message. Very flexible, possibly dangerous, but as only site admin can create git hooks this should be ok, I think.
or
b) the message is displayed in pre-formatted block which itself is centered however its content is left-aligned. So, in the example below, commits are nicely aligned one under another.

My suspicion is that a user could almost always get round this and end up causing unescaped strings

Did I get it right you suggest there is a way how to prepare error message so the markup is processed?
If so can you tell me how to make this work? I am not a golang-man...

echo "Foo <b>bar</b>" >&2
exit 1
