Describe the bug

Passing *emacs as the argument to nix-env --query crashes lix

Steps To Reproduce

  1. Evaluate $ nix-env --query '*emacs'

Note the quotes, otherwise a shell expansion might interfere if the current working directory has a file that matches that expansion.

Expected behavior

For lix not to crash. ej. print out

error: selector '*emacs' matches no derivations

nix --version output

the crash has been fixed in main, and the search being rejected is a feature (not a bug) dating back to 2014: nix-env uses regular expressions to match derivation names, * is merely special syntax to match all names (and not an indication that we search by globs). busted, but ancient
