"%" symbol does really weird things...

[AnotherRandomGitHubAccount]

When typing %, it usually doesn't appear, and depending on what you type next, weird things happen. for example if you press %b, it will make a long string of 1's and 0's. not sure if this is intentional and i just don't understand it, but i think that it should be fixed, but if there is a reason its there, it should be placed in the man page or in README.md

thats caused by vsnprintf it interprets % as the start of a format specifier
%b makes weird things happen (vsnprintf tries to interpret this as some format)
removing it fixes this:
