‣ : → \:
‣ alias → \alias
⇒ except in some internally used cases, where we use \builtin alias
‣ command . → \command .
• protect Korn Shell builtins from aliases and functions, e.g:
‣ typeset → \builtin typeset
⇒ also unravels the “local” alias used
‣ print → \builtin print
• protect internally-used things from aliases
‣ “let]” is not a valid function name
‣ “set” is POSIX so we don’t expect anyone to override it in a function
• use “command -v” instead of “whence -p” (“which”) in most
places; thanks izabera from #ed on IRC for pointing out
that “command -v” is POSIX – except, “whence -p” a̲l̲w̲a̲y̲s̲ looks
for an executable and shows its full pathname; “command -v”
also resolves to aliases, functions and builtins, so only use
it where it makes any sense (both never output to stderr)
• make most of dot.mkshrc work in the face of such aliases
‣ “ulimit -c” is used; this is not POSIX, and not portable;
maybe we should make ulimit accept-and-ignore the most
common limits even if the OS doesn’t use them?
• update list of builtin aliases in the manpage
