Different apps expect passwords in the .netrc file to be quoted in different ways. E.g. fetchmail expects passwords to be quoted in a bash style way (quotes needed if there are special chars, but quotes themselves need quotes), while cURL gives no special meaning to quotes and takes them literally if present.

Who to blame for this is a bit unclear, but I believe the original purpose of .netrc was for the standard CLI FTP program, so in principle everything should be aligned on that, IMO.

Some apps will complain if they spot a .netrc syntax they don’t like, as if they get to decide that -- even if the line it complains about is not the record the app is looking for. OTOH, it’s useful to know what an app accepts and rejects.

What a mess.
