Documentation -- msgh vs errfunc

[tehtmi <tehtmi@...>]

Hi,

I noticed this minor issue in the manual for Lua 5.2, but it still 
exists in 5.3-rc3.

The 4th parameter of lua_pcall is called "msgh", but the 4th parameter 
of lua_pcallk is called "errfunc". These should have the same name as 
they mean the same thing, and the documentation of one refers to the other.

It seems that msgh is now the preferred form since it was changed to 
this in 5.2 (along with related terminology), but errfunc may have snuck 
back in because it is still used in the source code to declare 
lua_pcallk. On that note, the name used in the documentation should 
match the declaration in the source code, so the source may need to be 
changed to use msgh as well. (This doesn't apply to lua_pcall since it 
is declared as a macro which may have contributed to this problem 
occurring.)

Thanks for your time,
