Both -G (gmtwhich) and -D (gmtget) already detect a missing file after gmt_download_file_if_not_found() (the not-found message, and the error lines it logs) but discarded that outcome and always returned GMT_NOERROR. Track it instead and return GMT_FILE_NOT_FOUND when a requested download did not produce the file. Scoped to -G/-D only (a plain "gmt which localfile" is unaffected) and gmtwhich -C keeps exiting 0, since its whole point is reporting Y/N as text. Tiled dataset listings are not covered here.

Proposes an answer to #9195:
gmt which -Gandgmt get -Dnow returnGMT_FILE_NOT_FOUND(16) when a requested download didn't produce the file, instead of always exiting 0 — both already detected the miss for their error messages, just discarded it. Scoped to-G/-Donly (plaingmt which <local file>is untouched),-Ckeeps exiting 0 since its job is reporting Y/N as text, and tiled dataset listings aren't covered. These are judgment calls, not answers from the issue thread — happy to adjust.Tested with:
