Command functions are traditionally named like the command shortened
to four characters. When this name collides with a keyword or library
function, we abbreviate more: brea(), rea(). A few are unabbreviated,
e.g. execute(). A few have different names, e.g. explain(), not
list().
Commit 23726b379 (v4.3.0) suppressed a GCC warning about carg()
colliding with its built-in function.
Ron Koenderink reported Microsoft Visual Studio 2019 fails to link:
"_carg already defined in ucrtd.lib(ucrtbased.dll)".
Time to clean this up: rename the functions to c_FOO(), where FOO is
the unabbreviated name of the command.
