Did you mean for this to go to the list (as other people might be
interested in the question and answer)?  And if so, please don't top-post.

strerror() is full of historical baggage - changing the strings it
outputs is not done lightly, even the string printed is not always the
best fit for all documented cases in which a particular error is
returned.  Thus, the man pages will ALWAYS be a better fit than what
glibc can cram into the limited abilities of strerror().

OK, thanks for that explanation Eric. In that case, my naive suggestion
would be to introduce a new glibc function, such as strerror_verbose.
