[nongnu] elpa/geiser-racket 7f89d8f 170/191: Use (car (process-lines ...)) instead of (shell-command ...)

[Philip Kaludercic]

branch: elpa/geiser-racket
commit 7f89d8f2049f6149618f32f47e1c80de586d7b51
Author: Jordan Brown <mrhmouse@gmail.com>
Commit: Jose Antonio Ortega Ruiz <jao@gnu.org>

    Use (car (process-lines ...)) instead of (shell-command ...)
    
    `shell-command` assumes Bourne-shell-compatible quoting, which
    doesn't work when the user isn't using a Bourne-compatible shell.
    
    Instead of futzing about with quoting, we can just use `process-lines`
    to execute a process and pass it arguments directly.
