Why not just invoke ‘make all’?

Also, phases no longer have to return #t

Why is ‘make all’ invoked in the ‘install’ phase?

Wouldn’t these things be handled by ‘make install’, assuming that
‘PREFIX’ and ‘SHARE_DIR’ are set correctly.

“Zsh” should be capitalized.

“This package provides syntax highlighting for Zsh.”

Capitalize “Zsh”.

‘COPYING.md’ says BSD-3.
