tests/openpgp-certs/testselfsigs sets "set -e" but later does:
This happens to work with bash because "unset" doesn't give an error
there if the variable wasn't defined before.
A regular/Posix sh gives a non-zero return code here, stopping the
script in its tracks due to the "-e".
for reference. The wording is somewhat poor because it says
"Unsetting a variable or function that was not previously set shall
not be considered an error and does not cause the shell to abort".
It is not about aborting in the common case but about the exit code;
the aborting would only due to the "-e".
Anyway, the sh and ksh implementations I found give a non-zero
return code in this situation.
Replacing the offending line with
unset RETCODE || true
fixes the issue.
