Catch error when application shebang contains space and print helpful error

[Gitznik]

How would this feature be useful?

Currently, if

• pipx installs its virtual environments under a path with spaces, and
• the installed application does not define an entrypoint and/or is invoked via one of its scripts

the execution fails with a bad interpreter error. See #1212 for more details.

Describe the solution you'd like

Catch this error and provide a more helpful error message. It should hint at setting PIPX_HOME to a path without spaces and raising this issue on the package that failed, with the context of our docs regarding developing for pipx.

Describe alternatives you've considered

None

See also pypa/pip#12599. It is possible to support spaces in the interpreter path, so that’s an option too.

I am trying to find a place where this error could be handled. Should it be during the install process itself ?

Probably, but we now print a warning whenever we detect a space in the pipx path, so I think this issue is no longer needed 👍
