Portability is a red herring. The function is guaranteed to exist by
the C standard. Portability of the *argument* (i.e. the value of
$EDITOR) is the responsibility of the user.

IMO safety is also a red herring -- as someone else said downthread,
the user can _already_ set $EDITOR to any value and have svn execute a
program based on that.

One remaining concern is quoting the filename argument. However, as I
understand it, $EDITOR is invoked only to generate log messages with,
which means Subversion controls the filename and can simply avoid
using shell metacharacters there.
