%default-port-conversion-strategy and string ports

[Ludovic Courtès]

Hello!

Commit b22e94db7c91d7661204e33f3bc2bfead002c9b7 adds
‘%default-port-conversion-strategy’, a natural friend of
‘%default-port-encoding’.

First, I’m wondering whether ‘port’ should be part of the name, given
that it’s also referred to by ‘scm_stringn’ & co.  It’s good to have it
in the name, for the symmetry with ‘%default-port-encoding’, but it’s
not accurate.

Second, in commit 9f6e3f5a997f484548bd03e7e7573c38a95c8d09, I changed
string ports to honor it, like other port types, instead of forcing
'error.  This seems like the right thing to me, for the sake of
consistency (in fact, I’d consider the previous behavior as a bug), but
it’s an observable change.

WDYT?

Thanks,
Ludo’.
