FS#41 - improve command-line parsing error messages
POV-Ray 3.6, upon encountering problems when parsing command line and/or .ini file options, would quote the offending option in the error message.
POV-Ray 3.7 currently just reports that there is some problem with the command line, without providing any details. I suggest changing this, as the information may be helpful at times.
IIRC this feature was added some time ago, wasn't it?
Don't know what I was seeing back then; I just tried a few things and can't reproduce it now (which fits the code as I see it, and as it seems to have been for ages).
Why is this considered a feature request rather than a bug? It is the failure/disabling of a feature that existed in 3.6.
The problem still exists in version 3.7.0 final. It is also inherited by UberPOV.
Re-opened: While the Windows version does a nice job reporting command-line errors, the Linux version doesn’t.
We should re-structure the code to have all versions share one and the same piece of code for command-line parsing (and related error-reporting).
Now tracked on github as issue #173.
