Depends on whether distinguishing the exit code 2 from the exit code 1 is
important.  Normally it isn't, but sometimes 2 is documented and then at
least the documentation should be changed too.

BTW, I glanced at this because it looked a bit like use of sysexits and
I don't like sysexits.  But sysexits exit codes start at 64 and are
almost perfectly undocumented in utilities that use sysexits.  I don't
mind using the Standard C EXIT_SUCCESS and EXIT_FAILURE although these
are just aliases for 0 and 1 and these aliases are also almost perfectly
undocumented (most man pages use the mdoc macro ".Ex -std" which expands
to "The <foo> utility exits 0 on success, and >0 if an error occurs."
POSIX also mostly says 0/>0.  Thus the values in sysexits are allowed,
but know one knows what they mean.
