Hide decorations in git log

[Robert Dailey <rcdailey.lists@gmail.com>]

Hello,

Is it possible to hide decorated refs in `git log` even if they are
reachable from the refs I'm actually interested in seeing the logs of?

For example, if I do `git log --graph --decorate --oneline --branches
'feature/*'`, I'd like to *only* see refnames that match the glob
pattern. However, you'll see tags and other branches that do not match
the glob if they are reachable from the result set.

This is purely a visual thing, and shouldn't impact the search results
I'd think.

This is especially useful in cases where I do --simplify-by-decoration
to get a better understanding of the topology of just a couple of
select branches. Without some sort of "decoration exclusion", I am
getting ton of results including tags, etc which obfuscates the
information I'm really interested in.

Thanks in advance.
