- Raise `CaskError` instead of `Plist::ParseError` from module - Improve error message when parse result is empty - remove leading garbage text and emit it to stderr (seen in #5060) - remove trailing garbage text and emit it to stderr (seen in #4819) This has the incidental effect of emitting DMG licenses during installation, which seems desirable as permanent functionality. If not permanent, the warnings to STDERR should still be kept temporarily to help get better bug reports on `hdiutil`. A bug wrt DMG licenses must have been introduced in one of #4892, #4887, #4889, #4900, #4975, #4978, or #4857. Presumably, the cause is that STDERR was previously silenced when running `hdiutil`. It would be cleaner (and more reliable) to redirect STDERR and examine it separately, rather than clean up the merged outputs. closes #4819 closes #5060
