Like tdump() and trestore() before commit 32d1abb1, sh_deparse() fails
to handle process substitutions correctly. This limitation of the shell
deparser is rather minor since it's unused. However, seeing as the
deparser was left in the code base intentionally it should at least
function properly.
src/cmd/ksh93/sh/deparse.c:
- Add a PROCSUBST flag for handling process substitutions in
sh_deparse().
- If we're handling a process substitution, add an ending ')'
without an extra newline.
- Avoid adding an extra ' &' to commands inside of a process
substitution. An extra ' &' is only added if the FAMP and FINT
flags are set, which indicates the command was spawned as a separate
job with '&'.
- Add process substitution handling to 'p_redirect' by calling p_tree()
when encountering a process substitution.
