Evaltree and its variants support three flags:
- EV_EXIT means to exit when evaluation is complete (for use by the
"exec" builtin, pipelines, and subshells).
- EV_TESTED means that this code is the argument to a conditional.
If some part of it fails and the -e flag is set, it will not cause
the shell to exit.
- EV_BACKCMD is an unused vestige from an experiment long past.
There has been no need to advertise the possible flags outside eval.c
so far because the only external callers, main and cmdloop, always
use 0 (no flags). Expose the flags in eval.h so that can change.
[jn: originally from Jilles as part of FreeBSD SVN r194128; split up
for clarity.]
