Description

Minimal reproduction: https://github.com/Thirdegree/shiv-issue-reproduction

Output when built with shiv<0.5.0 (expected output):

$ pip install 'shiv<0.5.0'                     
[...]
$ shiv -c example . -o my-other-example        
[...]
$ ./my-other-example                           
['./my-other-example']                         

and shiv>=0.5.0:

$ pip install 'shiv>=0.5.0'                                                                                                                 
[...]
$ shiv -c example . -o my-other-example      
[...]                                                                                               
$ ./my-other-example                                                                                                                        
['/home/<snip>/.shiv/my-other-example_4e97fbfbe05adc1827d2cf3da93d0600d4eb83fdb7b83d1230c1127d42c9e4e0/site-packages/bin/example']          

This seems to only be an issue when built with -c:

$ shiv -e reproduce.main:main -o my-example . 
$ ./my-example                                
['./my-example']

Research direction

Run the linked minimal reproduction with shiv versions before and after 0.5.0, comparing builds made with -c against those using -e. Trace the command-entry behavior involved in setting sys.argv[0]. Done means the -c-built executable reports its own invocation path, matching the expected output shown in the issue.
