Term-CLI-0.054001

Changes for version 0.054001 - 2022-01-04

Code Cleanup
- Tests and modules pass perlcritic's "stern" (-4) filter.
- Apply perltidy.
- Properly localise %SIG in `readline`.
- POD fixes.
- Remove unnecessary `else` and `elsif`.
- Run code through perltidy.
- Eliminate some unnecessary else/elsif.
- Remove default export of `loc` from `Term::CLI::L10N` Explicitly import `loc` in all modules that need it.
- Do not use `package Foo {}` syntax. All modules have only one `package`, so the block syntax doesn't add anything and causes perltidy to unnecessarily indent all code.
Enhancements
- Improve filename completion for non-GNU readline The glob variation now uses a trick when completing directory names that prevents the readline module from adding a space.
  - Files modified: lib/Term/CLI/Argument/Filename.pm
- Add CONTRIBUTING.md, Contributors; fix README
- Add a `clear_error` method to Term::CLI::Base and use it instead of `set_error('')`.
Bug Fixes
- Fix potential bug in line splitting (Term::CLI).
- Work around for old Pod::Text::Termcap, closes #12 Versions of `Pod::Text::Termcap` before 4.11 had a bug (#124447) that resulted in it using a screen width of 80, regardless of what was specified in the constructor call or environment. As a result, the high `=over` indents could cause very strange output or even make `Pod::Text::Termcap` spin into an eternal loop.
  - To make life easier for those with older Perl installations, we test for the older `Pod::Text::Termcap` version and use `Pod::Text::Overstrike` instead if necessary. The overstrike variant does not contain the screen width bug, although it does require a pager that understands overstrike sequences. The default pager for `Term::CLI` (`less`) does, so the invonvenience should be minor.
  - Thanks to djerius for reporting and diagnosing the problem.
