This is the latest scan of errors and oddities in regexps in the Emacs source tree.
New this time is an experimental check for branch subsumption: whether one branch in an or-expression matches a superset of another, like "[ab]\\|a". Please tell me if you believe this might be useful, so that I know whether to include it in the next release of xr.
The algorithm uses some simple linear heuristics since a full regexp subset check would be quite expensive and probably require DFA construction and graph equivalence; maybe something for a future version.

The hit for tramp-adb-prompt makes sense. I'll run some local tests,
after that I'll commit a change.
Best regards, Michael.

Thanks, these all look useful to me. I installed the attached patch to
fix the glitches.

Thank you, that patched seems fine to me. a59c41ee81 (cc-mode.el) has been pushed to complete the set.
The subsumption check will be included in a new xr release then.
