It is never a good idea to ignore errors, so let's handle them.
While at it, handle fopen() errors more gently (i.e. give the caller a
chance to do something about it rather than die()ing).
Note: there are more places in the builtin am code that ignore
errors returned from library functions. Fixing those is outside the
purview of the current patch series, though.
