Long ago, sh used to have its own optimized and restricted string formatting implementation, which the printf builtin had to bypass via asprintf() to a temporary buffer. Since sh has used libc's string formatting implementation for a long time, remove the workaround. Add a check to keep printf %c '' working the same way (output nothing); POSIX allows both outputting nothing and outputting a NUL byte. Also, this change avoids silently discarding format directives for whose output asprintf() cannot allocate memory. |
