When showing help, If terminal width is too low, clap goes into an infinite loop

[crumblingstatue]

If 01a_quick_example is invoked with the help subcommand on a terminal of width 34 or lower, clap goes into an infinite loop. It also keeps allocating memory.

[crumblingstatue]

this is the problematic loop.

Since this is a bigger issue this'll take priority but should also be an easy fix. Thanks again!

I have this fixed locally. Once I get home I'll put in the PR and put out 2.2.1 after the merge
