No but auto-generated completions are a best-effort situation. Man pages
vary greatly in how they express the arguments a command accepts. Fish's
auto-generated completions will sometimes be missing completely or
sub-optimal for some commands. Note that when asking such a question you
should always a) specify the fish version you are using, and b) the OS you
are using. In this case I can confirm that the newest fish version (from
git head) running on Ubuntu 16.10 fails to create a completion file from
the man page for the `readelf` command.
Feel free to open an issue at
https://github.com/fish-shell/fish-shell/issues/new asking that the
`fish_update_completions` command be improved to handle that man page or
requesting that a custom completion script be written. Note that the issue
is more likely to be resolved quickly if you're willing to create change to
the code :-)
