When the transaction is still pending, the past tense is incorrect.
This is not relevant for the contras, because those descriptions are
only displayed in logs, after the fact.
Originally, this command didn't have a description parameter. Foo would
use `give xyzzy 10 foo`. Then, a description parameter was added. For
backwards compatibility, if you would enter a username (like `foo` in
this example) in the place of the description, it would finalize the
transaction using that.
However, as the user base grows, several reasonable descriptions exist as
user account names, and that would finalize the transaction under the
wrong user.
It's time to break backward compatibility. If you don't want to leave a
message (it's still optional), that can be done with `x` (like the
`donate` command), or in advanced mode, with `""`.
Because it's likely that people are still very much used to just leaving
the description out, if you enter something that happens to match an
existing username, the input will be rejected.
The current equivalent command line would be `give xyzzy 10 ""; foo` or
`give xyzzy 10 x; foo`. If the `;` (new since v5.0.0) is left out, the
trailing `foo` has to be confirmed with a second press of the enter key.
The signatures feature has been "experimental" since Perl 5.20 (May 2014), but
expected to stay. After 8 years I'm ready to take the risk :)
Have added Perl v5.28 (June 2018) as the minimum requirement, even though the
current revbank should work with 5.20, to see if this bothers any users. Perl
v5.28 is in Debian "buster", which is now oldstable.
