- Authentication-results: sourceware.org; auth=none
Ref: https://sourceware.org/ml/gdb-patches/2015-07/msg00629.html
This fixes the bogus command line in the error message shown when the
SHELL environment variable points somewhere that's not something that
resembles a shell:
$ SHELL=/nonexisting gdb /home/pedro/a.out
(gdb) r
Starting program: /home/pedro/a.out
- Cannot exec /home/pedro/a.out -c exec /home/pedro/a.out .
+ Cannot exec /nonexisting -c exec /home/pedro/a.out .
Error: No such file or directory
During startup program exited with code 127.
