Effort is one thing, but in practice systems don't always provide
useful diagnostics and
the code would not be portable -- even a huge effort would not
suffice. Rather than list likely reasons, the message could say "If
you don't know the reason, ask a wizard for help."

Hopefully each user only needs to read the help text once. The main
advantage to encouraging the user to simply fix the problem and
continue is not saving time, but making the user aware of the specific
problem. If you just issue a message and abort the job, users tend to
ignore or overlook the message (e.g., because TeX is being run from an
editor and the shell window closes when the job exits). So it is
useful for the job to wait user for input.
Many users will type Ctrl-C or Ctrl-D without bothering to read
messages and expect the job to abort because that is common for other
I suspect that in the majority of cases, the user would prefer to fix
the problem and continue
with the original filename, so what about:
! I can't write on file `ex.aux'.
l.4 \immediate \openout \aux = ex.aux
If you don't know why you got this error, ask a wizard for help.
Enter `R' to retry after fixing the problem; any other response aborts the job:
