[PATCH 0/2] Make GPG errors less puzzling

For one times too many, I was asked to help with a commit signing problem where the only error message was an unhelpful:

error: gpg failed to sign the data fatal: failed to write commit object

That was it. No further indication what went wrong. And certainly not that wonderful error message that the helper that was configured as gpg.program wrote to its stderr.

Let's show whatever GPG (or any alternative configured via gpg.program) had to say when signing failed.

Johannes Schindelin (2):
  t7510: add a test case that does not need gpg
  gpg: do show gpg's error message upon failure
