Control the empty lines in the usage doc

[songtaogui]

The generated Usage contains many empty lines, I understand this may help for better layout when the usages are short. However, when the options gets complicated, the whole usage doc would become too long. Is there an option that I could control the empty lines?

for example, the generated usage of the Quick Start demo is:

  sum



Usage

  sum <args> [options] [flags]

Args

  <x>                                                       first number.

  <y>                                                       second number.



Options

  -p, --precision <type>                                    prescision of the calculation.



Flags

  -f, --fastmath                                            enable fastmath.

  -h, --help                                                Print this help message.
  --version                                                 Print version.

however, I prefer sth like:

  sum

Usage
  sum <args> [options] [flags]

Args
  <x>                                                       first number.
  <y>                                                       second number.

Options
  -p, --precision <type>                                    prescision of the calculation.

Flags
  -f, --fastmath                                            enable fastmath.

  -h, --help                                                Print this help message.
  --version                                                 Print version.

All the best!
Version of the package:

Status `~/.julia/environments/v1.9/Project.toml`
  [863f3e99] Comonicon v1.0.6
nothing

sorry for automatically labeled this issue as [bug], it is more like a [request]. lol

Yeah, this is because Comonicon was developed in pre-1.9 era, so we have to eliminate as much runtime as possible, resulting in non-adaptive printings. I believe in 1.9+ because of pkgimage, just doing dynamic printing can still have a reasonable latency. But I personally won't have much time working on this package this year. So any large changes will need to wait for next year after I graduate.
