Fri, 24 Jul 2026 17:19:48 -0700 

Follow-up Comment #2, bug #68560 (group groff):

The quoted fix also makes the error diagnostics more intelligible.


$ ../src/devices/grops/tests/device-extension-command-import-works.sh
>/dev/null
checking that 'ps: import' device extension command works
./grops:<standard input>:17: error: invalid argument 'a 203b 311c 408d 481e
144000f 119415g' to device extension command 'import'
./grops:<standard input>:18: error: invalid numeric argument(s) 'a' to device
extension command 'import'
