It seems to me that, ideally, attach should never attach anything that
send would reject as an error. Is this too unreasonable a requirement?
If you accept that requirement then, given the above about send, I suggest
attach should reject with, an error message, any:
Unreadable files (including directories)
Dangling symbolic links
Symbolic links to unreadable files (including unreadable directories)
Directories or symbolic links to directories, unless the -r option is given
Even though attach should check symbolic links, it should attach a
symbolic link to an ordinary file as the link itself. (This would allow
the link to have a different suffix then the file linked to). That's what
it does now.
If the -r option is given then attach should recursively attach all files
(including files whose names begin with '.' ?) in any directories encountered.
Since a simple error, could inadvertently generate hundred of attachments,
maybe attach should return with the number of files attached, when the -r
option is given, or perhaps always, for consistency.
Maybe requiring attach to not make send unhappy is overkill, and is not
worth the extra trouble?
