I think it would be better to just

 (a) get rid of the magic strcspn() entirely

 (b) make the 'can we optimize this' test be simply just looking up
'argv[0]' in $PATH

What about

        ABC=1 my-executable my-arg

What about it?

Do you have a binary like

    '/usr/bin/ABC=1 my-executable my-arg'

or something? If so, it gets executed. If not, it would get passed off
to "/bin/sh".

That sounds a lot more obvious than "some random set of characters are magical".
