This looks good, but in addition to the test case in the description, please add a couple of things to your test plan for SRU verification: 1) Dirk F's steps to reproduce in comment 2, because that's the real user impact for which we're doing this SRU. 2) I agree with your assessment under "Regression Potential", so in mitigation please also exercise some other cases of ghostscript command line parsing - for example without '--' - that other tools might use, to ensure that we aren't regressing them. ** Description changed: [Impact] - * The command line syntax `gs [options] -- ` fails -to load in the input file with a "permission denied" error. - * Per the ghostscript documentation, the `--` syntax is used as follows: - "-- filename arg1 ... -Takes the next argument as a file name as usual, -but takes all remaining arguments (even if they -have the syntactic form of switches) and defines -the name ARGUMENTS in userdict (not systemdict) -as an array of those strings, before running the -file.
