pub fn execshfunc(shf: &mut shfunc, args: &mut Vec<String>)Expand description
execshfunc(Shfunc shf, LinkList args) — Src/exec.c:5540.
Promoted to top-level pub fn so execcmd_exec at the shfunc
dispatch site (c:4102-4105) can route through it. The real port
owns queue_signals + cmdstack + sfcontext setup before calling
doshfunc; doshfunc itself is unported, so we route the body
through runshfunc (exec.rs:1700), which carries the
wrapper-chain + zunderscore restore. Degraded vs C (no cmdstack
push, no sfcontext flip, no XTRACE arg-trace) but the function
body executes and lastval is updated.
