Sorry for not replying to that earlier.

I'm afraid it's effectively the same thing as using shell-quote-argument
directly in my code.  It puts the responsibility on me, because if
shell-quote-argument breaks and I don't react fast enough to change
shqq--quote-string, it's my fault for having used a definition of
shqq--quote-string that was prone to breakage.


To clarify, all this "responsibility" stuff I'm talking about is not
about putting blame on people *after* a serious bug has happened.  It's
about APIs declaring their semantics (responsibilities) very precisely,
and programmers accordingly choosing the right API for their task, so
the responsibility of upholding a certain invariant is offloaded to the
implementation of that API.

Just a more pedantic way to look at the basic idea of abstraction
really, which is necessary here because of security concerns.

Responsibility of and blame on programmers serves as a less boring way
to explain it. :-)
