For example, some days ago I was seeing this error:
Error in post-command-hook (completion-in-region--postch): (wrong-type-argument
characterp 134217855)
and it turned out the error was generated by another function 100 miles
from completion-in-region--postch. debug-on-error is mostly useless in
this case.
Can post-command-hook errors be more informative? Thanks.
