I consider temporary files to be more fragile -- you have to take care
of file permissions, removing the file afterwards even after an
interrupt with C-c, deleting the temporary file can fail, there might
be an out-of-space error, in case of file system corruption things
might be remounted read-only, some other program could read, write or
delete the file ..., so I think it would be best to just fix the bug in
dash instead.
