pub static esprefork: Atomic<i32>Expand description
Port of static int esprefork, esglob = 1; from Src/exec.c:2680.
File-static “execsubst parameters” — callers (execcmd_exec at
c:3298 / c:3700) set these BEFORE invoking execsubst, which then
uses them as the flags arg to prefork() and the gate on
globlist(). esprefork is PREFORK_TYPESET for magic-assign /
MAGICEQUALSUBST words, else 0. esglob defaults to 1; cleared
when the dispatched builtin has BINF_NOGLOB.
