Incorrect footer parsing

[rosen-kanev]

Hey 👋! I'm using a downstream package git-cliff which produces incorrect output when parsing such commit messages:

fix(example): fix keepachangelog config example

Fixes: #123, #124, #125

and the author of git-cliff helpfully redirected my question to here since the parsing apparently happens via git-conventional. Here's the full context orhun/git-cliff#130.

I carefully went through the Conventional Commits specification here and also here and I'm under the impression that Fixes: #123, #124, #125 should be a valid trailer with a token "Fixes" and a value "#123, #124, #125".

As a sanity check, @conventional-commits/parser does exactly that https://runkit.com/embed/212h966ic1s1
So does git's built-in parser:

message="fix(example): fix keepachangelog config example\n\nFixes: #123, #124, #125"
echo $message | git interpret-trailers --parse # Fixes: #123, #124, #125

Any chance that git-conventional just assumes the trailer value ends on whitespace?
