Fix the build for variants that do not define EDIT.

Update editing before prompt printing.

defer editing setup/cleanup to when we are interactive.

Use the right size for several calloc calls.

When allocating for a Char **, it should use sizeof(Char *), not
sizeof(Char **). This doesn't actually affect the results except
on DS9000 though :-)

(part 2, the instance in this file was as far as I can tell
inexplicably missed by CVS on the first go...)

Clarify some comments.

Don't cast the value returned from *malloc. No change to compiler output.

Don't depend on common declarations.

remove unused

Welcome to the 21th century csh: retire "ptr_t" now that we have "void *"

Remove Free, s/xfree/free/.

Standard C says that free should be a no-op for a NULL pointer, so
we don't need an extra function to do this.

While here, add an XXX about a wrong sounding comment

WARNS=6 [-Wconversion]

make history kind of work :-), turn libedit support on.

Add a little libedit front end. Could be used as someone's pet project to
learn how to program. It is not enabled in the Makefile, and it states why
there.

From tnozaki@: make fpos_t a complex object that keeps track of the parse
state of the stream. Change argument of the seek function to funopen() from
fpos_t to off_t. Make f{g,s}etpos() use the new f

From tnozaki@: make fpos_t a complex object that keeps track of the parse
state of the stream. Change argument of the seek function to funopen() from
fpos_t to off_t. Make f{g,s}etpos() use the new fpos_t struct, while providing
backwards compatible entry points. Approved by releng@

Use __dead

Remove the \n and tabs from the __COPYRIGHT() strings.

no need to have cshbool; just make them int

PR/36650: Michael van Elst: Get rid of bool, because csh uses bool as a small
int.

Rename bool -> cshbool; despite the name, bool actually holds values other
than 0 or 1. Fixes PR/36650.

It's "its."

sprinkle a little const, and now everything compiles with WARNS=3

Deal with RESCUE

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22249, verified by myself.

Rename `sigset' locals to avoid symbol shadowing warning.
