If flags and params are too long, description is missing from help output

[AloeareV]

When Options is derived, the usage() output will have an extra \n after long_param if -short, --long long_param is longer than 29 characters. This causes long_param to be set to None, description to be set to what should be long_param, and the actual help description from that flag to be missing from the help output entirely.

Using lines() here doesn't work:

abscissa/core/src/command/usage.rs

Line 350 in bee6525

for line in usage.lines() {

The longer-term solution to these sorts of issues is an eventual migration to clapv3. See #298 and #330.

For the interim issues like this are unlikely to be solved unless you'd like to submit a PR.
