gpg will timeout when asking for a PIN. This is annoying when you are encrypting x00GB of data taking half an hour to timeout afterwards asking for the passphrase just for one minute.
'--timeout SECONDS' To disable the timeout and wait indefinitely, set this to 0, which is the default.
Sure the other option is to fix the documentation (T5548). Then one would need:
echo 'pinentry-timeout 0' >>~/.gnupg/gpg-agent.conf
But personally I find more infinity as a better default.
